Simple little exercise 1:

sex = input( " Please enter your gender: " )
 if sex== " Male " :
    height =input( " Please enter your height (cm): " )
    salary =input( " Please enter your salary: " )

         print ( " Hello, Gao Fushuai " ) 

if sex== " female " :
    skiny_color =input( " Are you white? " )

Simple Exercise 2: Printing the Nine-Nine Multiplication Table

i = 1
while i <= 9:
    j=1
    while j <= i:
        print("%d*%d=%d\t"%(j,i,j*i),end="")
        j+=1
    print("")
    i += 1

 Simple Exercise 3: Rock Paper Scissors Game

Introduce the random function, random.randint(0,1): Randomly obtain integer numbers between 0 and 1

import random #Prompt
 and get user input 
player=int(input( " Please input: 0 scissors 1 rock 2 cloth: " ))

compter = random.randint(0,2 )
 # Judge the user's input, and then display the corresponding result 
# if the player wins the condition: 
if (player == 1 and compter ==0) or (player == 2 and compter == 1) or (player == 0 and compter == 2 ):
     print ( " Congratulations, you won " )
 # elif conditions for a draw: 
elif player == compter:
     print ( " It's a draw, wash your hands, the final battle is over Dawn " )
