1. I think Python + C is better
from the perspective of people around me, I come to the following point of view:
C + +: learning can solve any problem, that is, the cost of learning is too high, the time and brain power are not enough, learning is not good
Python + C: take a project, first make a trial version with python (regardless of execution efficiency, memory, etc.), the development speed is ten times the development time of other languages, and then test it. If there is a bottleneck in the implementation, either open a few more processes, or use C language to write small functions, and then call it with Python, almost any problem can be solved quickly and well To improve the speed, try pypy)
go: it has always been emphasized that go is more efficient for multithreading and multi CPU execution than many blocks. That's because compared with Python, python doesn't support multithreading at all (because of the existence of GIL). Go is mediocre in all aspects (the efficiency is less than C, and the support of library is less than python (Python can also use C Library)), It's just better than Python's lameness< In other words, it feels like driving a tractor full of stones

general feeling: Genius to learn C + +, can solve any problem, and make a lot of money; I am not a smart person, python + C can solve almost all problems...
2. Go1.1 is coming soon. It is estimated that the performance will be improved by 30% - 40%. Python is not at the same level at all
the code is simple and easy to write. It's very good!
3. Go has slicing slice type, python has list and tuple, both languages have slicing operation
but their slicing operations are completely different
first of all, the members of go are of the same type, while the list and tuple of Python do not limit the type
both languages have the slicing operation of [A: b], and the meaning is similar, but the A and B parameters of go cannot be negative, and python can be negative, which is equivalent to counting from the end to the front
both languages have the slicing operation of [A: B: C], but the meaning is completely different. C of go represents capacity; Python's C represents the step size
but the biggest difference is that the slicing of
Python generates new objects, and the operation on the members of the new objects does not affect the old objects; The slicing of go proces a reference to a part of the old object, and the operation on its members will affect the old object
the reason is that the underlying implementation is different
for the slice of go, the bottom layer is a triple, a pointer, a length and a capacity. Pointer to a block of continuous memory, length is the number of existing members, capacity is the maximum number of members. When slicing, it does not apply for new memory. Instead, it moves the original pointer and returns a slice type value with the new length and capacity. In other words, the slice operation of go usually shares memory with the slice that generated the slice
it's not only slicing, but also slicing of strings and arrays, which usually share memory
of course, there are some exceptions, that is, when slicing, if the capacity provided is too large, new memory will be applied and copied; Or if the slice append exceeds the capacity, the same will be true. At this time, the new slice will not share memory with the old slice If the capacity you provide when slicing / creating is less than the length, the list of
Python is actually a pointer array. Of course, there will be some vacancies in the lower layer, but it is basically an array. Slice them and create a new array. Note that you create a new array! Python lists don't have the concept of capacity
this also reflects the difference between scripting language and compiling language. Although both languages have similar slicing operations; But the main goal of Python is convenience; The main goal of go is to be fast (and make up for the defect of discarding pointer operation). a

5. If the amount is not particularly large, and the buyer does not ask for capital supervision, it is not necessary to do capital supervision. To get the down payment is your money. When you hand over the house to the buyer, you usually wait until you receive the final mortgage from the bank. So there's no risk for you.
6.
  1. the down payment of second-hand house is both cash and bank card transfer

    The process of second-hand house transaction is as follows:

    (1) the buyer and the seller establish information communication channels to understand the overall status and property rights of the house, and require the seller to provide legal certificates, including house ownership certificate, second-hand house transaction process certificate and other certificates

    (2) if the house provided by the seller is legal and can be traded on the market, the buyer can pay the house purchase deposit (paying the house purchase deposit is not a necessary procere for the sale of commercial housing), and the buyer and the seller sign the house sale contract (or house sale contract). After the buyer and the seller reach an agreement on the location, property status, transaction price, delivery time, delivery and property right handling of the house through negotiation, the two parties shall sign at least three copies of the house sales contract

    (3) the buyer and the seller jointly apply to the real estate transaction management department for examination. After the buyers and sellers apply to the real estate management department, the management department shall check the relevant certificates, examine the property rights, permit the transfer proceres for the houses that meet the listing conditions, and refuse the application in case of no or partial property rights and without the written consent of the co owners of other property rights, so as to prohibit the listing transaction

    (4) contract. The real estate transaction management department shall, according to the property right status of the transaction house and the purchase object, apply for the approval level by level according to the approval authority set by the transaction department in advance. Only after the approval, can the transaction parties go through the contract proceres. Now Beijing has cancelled the real estate sales contract in the transaction process, which is commonly known as "white contract"

    (5) pay taxes. The composition of tax and fee is complex, which depends on the nature of the transaction house. For example, the tax and fee composition of housing reform housing, dilapidated housing, affordable housing and other commercial housing is different

    (6) handle the transfer proceres of property rights. After the registration of property right change in the real estate transaction management department, the transaction materials shall be transferred to the certificate issuing department, and the buyer shall apply for a new property right certificate at the certificate issuing department with the notice of getting the house ownership certificate

    (7) for the buyer of the loan, after signing the house sales contract with the seller, the buyer and the seller jointly go to the loan bank to handle the loan proceres. The bank reviews the buyer's credit, evaluates the house to be traded by both parties, so as to determine the buyer's loan amount, and then approves the buyer's loan. After both parties complete the change of property right registration, and the buyer obtains the house ownership certificate, the buyer can apply for the loan, The bank will issue the loan in a lump sum

    (8) after the buyer gets the house ownership certificate, pays off all the house money, and the seller delivers the house and settles all the property fees, the second-hand house sales contract of both parties is completed

7. There may be bank rebate, he can get more rebate, but this is what happens with loans. There's something wrong with that one. Or pay attention and ask him why?
8.

It is suggested to judge whether it is fraud from the following two points:

  1. whether it promises high returns

  2. whether there is a high head pulling rebate mode

  3. < / OL >

    if there are the above two points, it can be judged that it is a Ponzi scheme, and most of the people involved will be buried
