HowTo: Python Convert a String Into Integer

To convert a string into an integer in Python, you can use the int() function. This function takes a string as an argument and returns the corresponding integer value.

Here's an example of how to use the int() function to convert a string into an integer in Python:

# Convert a string into an integer
string = "123"
integer = int(string)
print(integer)  # Output: 123

You can also use the int() function to convert a string that contains a hexadecimal number into an integer. To do this, you can use the base parameter and specify a base of 16. For example:

# Convert a hexadecimal string into an integer
hex_string = "0xFF"
integer = int(hex_string, base=16)
print(integer)  # Output: 255

It's important to note that the int() function will raise a ValueError exception if the string cannot be converted into an integer. To handle this exception, you can use a try-except block. For example:

# Convert a string into an integer, handling the ValueError exception
string = "abc"
try:
    integer = int(string)
    print(integer)
except ValueError:
    print("Invalid string")

This will print Invalid string if the string cannot be converted into an integer.

It's also important to note that the int() function can only convert strings that contain numeric characters into integers. If the string contains non-numeric characters, the int() function will raise a ValueError exception.
