The path to PYTHON's automated learning

One, user interaction small Program

' GYC '  'gyc'= input ("What are youname?:"  = input ("mima:")print(u,p)

Second, if...else process judgment

#!/usr/bin/env python3.5#*-* coding:utf-8 *-*GYC= 18 Age= Int (Input ("Please enter the age of GYC:"))ifAge = = 18: #判断用户输入的值是否与初始值匹配Print("very good!")Else: #否则, Error! Print("I'm sorry, you're not gyc!. ")

Three, while Loop example

GYC = 18NUB=0 whileTrue:#the loop condition is trueNUB + = 1ifNUB = = 3:        Print("End")         Break Age= Int (Input ("Please enter the age of GYC:"))    ifAge = = 18:        Print("very good!")    Else:        Print("I'm sorry, you're not gyc!. ")

Equivalent to the following program

1. Optimize while loop code

#!/usr/bin/env python3.5#*-* coding:utf-8 *-*GYC= 18NUB=0 whileNUB <= 3: Nub+=1 Age= Int (Input ("Please enter the age of GYC:"))    ifAge = = 18:        Print("very good!")    Else:        Print("I'm sorry, you're not gyc!. ")

Iv. Break and Continue

Break action to end the current loop

Sample Code,

GYC = ('I Love You') Nub=0 whileNUB < 4: Nub+ = 1g= Input ("Please input I love you in English:")    ifG = =GYC:Print("I Love You Me too!")        Break #当然输入的与初始化的匹配, end the loop, do not go down    Else:        Print("Please input I love you")

Continue

Jump out of the current loop

Sample Code,

 for  in range:    if i% 2 = = 0:        continue  #当 I divisible 2 o'clock  jump out of the current loop to perform the next condition 
        Print(i)
Output is 1 3 5 7 9
