Python process processing

Python process processing

1. Process processing If...else

#!/bin/bash/env python#_*_ coding:utf-8 _*_#python version:p ython3.6import GETPASSN1 = "abc" p1 = "123" name = input ("Input Your name: ") passwd = Getpass.getpass (" Input your passwd: ") if name = = N1 and passwd = = P1:print (" Welecome login! ") Else:print ("User or pass is incorrect")

2. Process processing If...elif...elif...else

#!/bin/bash/env python#_*_ coding:utf-8 _*_#python version:3.6n1 = 21name = Int (input ("Please input ' the number which you w Ant to: ")) if name = = N1:print (" You Are too smart! ") Elif Name < 21:print ("is too small!") Else:print ("It is too big!")

3.for Cycle

Example 1:# Loop 10 Number i = 1for i in range: print (i) Example 2: #猜年龄优化for ... break# can enter 10 opportunities, enter the correct exit. N1 = 21for i in range: name = Int (input ("Please input the number which your want to:")) if name = = N1:pri        NT ("You are too smart!")    Break    Elif Name < 21:print ("is too small!") Else:print ("It is too big!")

4.while Cycle

#!/bin/bash/env python#_*_ coding:utf-8 _*_#python version:3.6 Example # loop number, when loop 10 exits count  = 0# Set counter While true:    print ("Print:"  ,count)      count +=1    if count == 10:         print ("loop completed")         break;          #跳出循环例2 # Guess age game, you can enter 10 times, but the wrong 3 times to exit. N1 = 21count = 0while true:    if count < 3:         name = int (Input ("please input the  Number which you want to: "))         if name  == n1:            print ("You are  too smart!
