In Python, we can use int() to convert a String to int.

# String
num1 = "88"
# <class 'str'>
print(type(num1))
# int
num2 = int(num1)
# <class 'int'>
print(type(num2))

1. Example

A Python example to add two numbers.

1.1 Add two String directly.

num1 = "1"
num2 = "2"
num3 = num1 + num2
print(num3)

Output

12

1.2 Try it again with int()

num1 = "1"
num2 = "2"
# convert string to int
num3 = int(num1) + int(num2)
print(num3)

Output
