如何连接str和int对象? (4个答案)

4年前关闭。

我目前正在学习Python,所以不知道发生了什么。

num1 = int(input("What is your first number? "))
num2 = int(input("What is your second number? "))
num3 = int(input("What is your third number? "))
numlist = [num1, num2, num3]
print(numlist)
print("Now I will remove the 3rd number")
print(numlist.pop(2) + " has been removed")
print("The list now looks like " + str(numlist))

当我运行该程序时,输入num1,num2和num3的数字,它将返回以下内容:Traceback(最近一次调用为last):

TypeError: unsupported operand type(s) for +: 'int' and 'str'

问题答案:

您正在尝试连接一个字符串和一个整数,这是不正确的。

更改print(numlist.pop(2)+" has been removed")为以下任何一项:

明确intstr转换:

print(str(numlist.pop(2)) + " has been removed")

使用,代替+

print(numlist.pop(2), "has been removed")

字符串格式:

print("{} has been removed".format(numlist.pop(2)))
