Question

为什么在输入int后下面的代码卡住了。或str升华文字？相同的代码可以在python3命令行或pycharm上正常运行。

print ('\n asks for an integer and prints the square of it\n')
def square(num):
    return num **2

def ask():
    while True:
        try:
            usr_input = int(input('Input an integer:'))
        except:
            print (f'An error occurred! Please try again!')
            continue
        else:
           return (f'Thank you, your number squared is:{square(usr_input)}')
print(ask())

Answer 1

       return (f'Thank you, your number squared is:',square(usr_input))
print(ask())

您需要使用平方函数。希望对您有所帮助。

Answer 2

这是您的代码 只需做一下 square（usr_input））并删除花括号

 print ('\n asks for an integer and prints the square of it\n')
def square(num):
    return num ** 2

def ask():
    while True:
        try:
            usr_input = int(input('Input an integer:'))
        except:
            print ('An error occurred! Please try again!')
            continue
        else:
            return ('Thank you, your number squared is:',square(usr_input))

print(ask())

输出-

asks for an integer and prints the square of it

Input an integer:5
('Thank you, your number squared is:', 25)
