可変Pythonで文字を数える

Question

私は、テキストの行を一定の時間印刷するプログラムを作成しようとしていますが、最初のテキストエントリの文字の量を制限したいと思います。

コード：

# Hello World Script 2.0 

import random 
**------------------------------------------------ 
#i want to limit the amount of characters, how? 
------------------------------------------------** 
print("What do you want to be printed?(Max 20 Characters)") 
var0 = input("> ") 

print("Please enter the amount of times you want that printed(max 100000)") 
print('Or enter "R" for a random number') 
var2 = input("> ") 

if int(var2) > 100000: 
    print("That number is too high, please restart the proram and enter something smaller.") 
    exit() 

if var2 == "r": 
    var2 = random.randint(1,100000) 


var1 = var0 * int(var2) 
print(var1, var2) 

Answer 1

あなたは（）関数のLENと文字列の長さをチェックすることができます。

import random 
**------------------------------------------------ 
#i want to limit the amount of characters, how? 
------------------------------------------------** 
print("What do you want to be printed?(Max 20 Characters)") 
var0 = input("> ") 

if len(var0) > 20: 
    print("That is too long") 
    exit() 

print("Please enter the amount of times you want that printed(max 100000)") 
print('Or enter "R" for a random number') 
var2 = input("> ") 

if int(var2) > 100000: 
    print("That number is too high, please restart the proram and enter something smaller.") 
    exit() 

if var2 == "r": 
    var2 = random.randint(1,100000) 


var1 = var0 * int(var2) 
print(var1, var2)
