How can I convert a String to an int? "1234" → 1234

 

In Python, you can convert a string containing an integer to an actual integer using the int() function. Here's how you can do it with an example:

python

# Convert a string to an int
string_number = "1234"
integer_number = int(string_number)

print(type(integer_number))  # Output: <class 'int'>
print(integer_number)        # Output: 1234

In the example above, the int() function is used to convert the string "1234" to the integer 1234. The result is stored in the integer_number variable.

Keep in mind that if the string does not represent a valid integer, a ValueError will be raised. For example:

python

string_number = "hello"
try:
    integer_number = int(string_number)
except ValueError:
    print("Invalid integer format")

In this case, attempting to convert the string "hello" to an integer will result in a ValueError being caught and the message "Invalid integer format" being printed.
