python - 如何使用python中的运算符打印变量输入

Question

我的目标是执行以下说明:

Enter integer:

4

You entered: 4

4 squared is 16

And 4 cubed is 64 !!

Enter another integer: 5

4 + 5 is 9

4 * 5 is 20

这是我的代码:

user_num = int(input('Enter integer:\n'))
    
print("You entered: ", user_num)
    
print(user_num, "squared is ", user_num*user_num)
    
print("And", user_num, "cubed is", user_num*user_num*user_num, "!!")
    
user_num2 = int(input("Enter another integer:\n"))
    
print(str(user_num) + str(user_num2), "is", user_num+user_num2)
    
print(str(user_num) * str(user_num2), "is", user_num*user_num2)

问题是我代码的最后两行没有给我我想要的。我希望 user_num 和 user_num2 的输入以非连接方式打印并且不执行读取，例如，“4 + 3 是 7”和“4 * 3 是 12”。任何帮助将不胜感激。谢谢

利用 f-strings所以你的打印结构更容易生产。
更正后的解决方案如下所示:

user_num = int(input('Enter integer:\n'))

print(f"You entered: {user_num}")
print(f"{user_num} squared is {user_num**2}")
print(f"And {user_num} cubed is {user_num**3}!!")

user_num2 = int(input("Enter another integer:\n"))

print(f"{user_num} + {user_num2} is {user_num+user_num2}")
print(f"{user_num} * {user_num2} is {user_num*user_num2}")
