Partial Function- when a function has too many arguments to simplify, use the functools.partial You can create a new function that can fix some of the parameters of the original function, making it easier to invoke.
Import Functools
Int2 = functools.partial (int,base=2)
print int (' 1000000 ', 2)
# 64
Print Int2 (' 1000000 ')
# 64
A simple summary of the role of functools.partial is to fix certain parameters of a function (that is, set de

Getting started with Linux: Installing VMware 10 on CentOS 7
Install VMware 10.0.3 on CentOS 7. Let me introduce my experience. Generally, this version does not work on CentOS 7 because it can only run on a lower kernel version 3.10.
First, download and install it in normal mode (no problem ). The only problem was when we ran the VMware program later.

map()The function receives two parameters, one is a function, the other is a sequence, map Functions the passed-in function sequentially to each element of the sequence and returns the result as a new list.
defNum(x):ReturnX*XPrintMap(num,[1,2,3,4,5,6,7,8,9])# [1, 4, 9, +, A, $, +,--]
reduce()A function that acts on a sequence [X1, x2, x3 ...] , the function must receive two parameters, and reduce calculates the result and the next element of the sequence, and the effect is:

Getting started with Python (10) using list and tupleListOne of the data types built into Python is the list: lists. a List is an ordered set of elements that can be added and removed at any time .For example, by listing the names of all the classmates in the class, you can use a list to Indicate:>>> classmates = [‘Michael‘, ‘Bob‘, ‘Tracy‘]>>> classmates[‘Michael
Exercise 2-10 Arrangement (permutation)The 1,2,3,...,9 consists of 3 three-digit ABC, DEF, and Ghi, each using exactly once, requiring Abc:def:ghi = 1:2:3. Outputs all solutions. Tip: Don't have to be too much of a brain. Problem Solving Ideas:
First, the ABC minimum can only be 123, the maximum value of 329, to comply with test instructions.
The key to the problem is that each number in 1-9 must appear and cannot be duplicated. Workaroun
