Python Notes-Loop
Condition judgment and indentation, pay attention to colons
Increase the number of times limit
# guess the number
Lucky_num = 19
Input_num =-1
# limit the number of times
Count = 0
# while Luckynumm inputroomnum and count
< 3: while count < 3: input_num = int(input("please input your lucky_num:")) if input_num < lucky_num: print("please input big num") elif input_num >Lucky_num:
Print ("please input little num")
Else:
Print ("great")
Break
Count + = 1
Print (count)
Else:
Print ("too many counters are responsible for everything!")
Note indentation. Python is a language sensitive to indentation.
Note: ctrl+/
For cycle
# limit the number of times
For i in range (3):
Input_num = int (input ("please input your lucky_num:"))
If input_num
< lucky_num: print("please input big num") elif input_num >Lucky_num:
Print ("please input little num")
Else:
Print ("great")
Break
Else:
Print ("too many counters are responsible for everything!")
