Python full stack development Whlie loop

Whlie Condition # (when the condition is true) #break force terminate loop: #continue jump out of the current loop:

Print ("num") # (Output num)

Cases:

Output 1 to 100 even

num = 1

Whlie Num <= 100:

If num%2 = = 0:

Print ("num")

Num+=1

　　

Cases:

Yonghu = 1093166587
Mima = 123456789

While True:
AA = Int (input ("User name:"))
bb = Int (Input ("Password:"))
if AA = = Yonghu:
Print ("Welcome to this page")
Break # break terminates the loop;


Else
Print ("Input error")
Print ("")

Example: #嵌套循环:

height = Int (input ("Height:"))
width = Int (input ("WIDTN:"))

User_height = 1
While user_height <= height:
User_width = 1
While User_width <=width:
Print ("#", end= "")
User_width+=1
Print ("#")
User_height+=1
