python輸入錯誤檢查

Question

你好，我想讓我的輸入只允許整數，一旦它超過10，它顯示錯誤，任何援助將不勝感激。

square_ct = input("Enter an integer from 1-5 the number of squares to draw: ") 
triangle_ct = input("Enter an integer from 1-5 the number of triangles to draw: ") 

while square_count(input) > 10: 
    print ("Error!") 
    square_count=input() #the statement reappears 

while triangle_count(input) > 10: 
    print ("Error!") 
    triangle_count=input() #the statement reappears 

Answer 1

我的首選方法是使用while True環路與一休：

while True: 
    square_ct = input("Enter an integer from 1-5 the number of squares to draw: ") 
    if square_ct <= 10: break 
    print "Error" 

# use square_ct as normal 

或者Python的3：

while True: 
    square_ct = int(input("Enter an integer from 1-5 the number of squares to draw: ")) 
    if square_ct <= 10: break 
    print("Error") 

# use square_ct as normal
