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

Question

I am currently learning Python so I have no idea what is going on.

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))

When I run the program, entering in numbers for num1, num2 and num3, it returns this: Traceback (most recent call last):

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

Solution 1

You're trying to concatenate a string and an integer, which is incorrect.

Change print(numlist.pop(2)+" has been removed") to any of these:

Explicit int to str conversion:

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

Use , instead of +:

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

String formatting:

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

Solution 2

try,

str_list = " ".join([str(ele) for ele in numlist])

this statement will give you each element of your list in string format

print("The list now looks like [{0}]".format(str_list))

and,

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

print("{0} has been removed".format(numlist.pop(2)))

as well.

str(numlist) does certainly not result in an exception (even though it might not be what OP is after).
