python list for loop

This article describes the python for loop. The for loop is used to iterate projects in the python set, including the python tuple, string, and list container types discussed in the previous article "explore

#python中, the While statement is used to loop the execution of a program that, under certain conditions, loops through a program to handle the same tasks that require repeated processing.#while是 the "as type" loop structure.I=1While iPrint (i,end= "")I+=1Sum=0I=1While iSum+=iI+=1ElsePrint ("\ n", sum)Print ("0+2+...+100=", sum)#从控制台录入一个数字, the factorial from 1 to

I just looked at Python's while and for loop today, so I'm going to write it down:The while statement is a loop condition statement in Python, while judging the condition:PassBreakFor example:i = 1sum = 1While I j = 1While J sum = J * IPrint "%d *%d =%d"% (i, J, Sum),J + = 1i + = 1print "\ n"While statements can be nested IF statements, you can make various judgm

This article mainly introduces the use of the for loop in Python, from the technical documentation on the IBM official website. for more information, see For loop The article "explore Python, Part 1: Program with Python" in the previous sections of this series discusses if

The most basic syntax format in Python is probably indentation. Common loops in Python: for loops, if loops. A little game illustrates the use of for,if, break.Guess number game:1. The system generates a random number within 202. The player has 6 chances to guess, each guess will have feedback results, guess big, guess small or guessed right-end3.6 Chances, guess right, player wins4, 6 chances, no guess, sy

Article Title: List is used as a loop in Unix. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. When developing applications in Unix operating systems, loop statements can be said to account for half of the total. Because the U

>>> A = [1,2,3,4,5,6]>>> for item in a: ... A.remove (item) ... >>> a[2, 4, 6]Does it feel strange to see the code above? Intuitively, we just want to remove each element of queue a sequentially, in turn, and why the final result is [2,4,6]? If you have enough wit, you should guess what the reason is. For each for loop, the current time a. After the Remove (item) execution is complete, a is relatively shortened, and the element following the i

In some cases, we need to do something about the list, such as multiplying each element in the list by 2, which is generally the traversal of each element multiplied by 2. Then it will be two lines to write it down. And this will modify the original list, if you want to not modify the original list, there are more than
