#Convert string to int python 2 how to

The int() function supports base conversion for integers represented in different numeral systems.

If the string includes any non-digit characters (excluding the base prefix, e.g., ‘0b’, ‘0x’), Python will raise a ValueError.

The int() function can only convert strings that represent valid integer values.

Here are some key points to remember about the int() function: Always remember to specify the appropriate base for the conversion process.

In the example above, the octal string “173” is converted to its decimal integer equivalent, 123. Here’s how you can do it: oct_string = '173' Let’s look at another example.įor converting an octal (base 8) string to an integer, we use the int() function and set the base parameter to 8. In this example, the hexadecimal string “1A3” is converted to its equivalent decimal integer, 419. Hexadecimal_num = int(hex_string, base=16) Note: The int() function assumes base 10 by default, so you don’t need to specify a base when converting a string that’s in base 10 already.Ī hexadecimal (base 16) string can be converted to an integer using the same int() function, with the addition of specifying the base parameter as 16.Ĭonsider the example below: hex_string = '1A3' You can perform these conversions using the following syntax.

#Convert string to int python 2 how to

In this section, we’ll cover how to convert strings in different bases to base 10 integers in Python, including decimal, hexadecimal, and octal conversions. Output: 1001 Conversion with Different Bases Keep in mind that the string must represent a valid integer value for the conversion to succeed. The general syntax looks like this: integer_value = int('string_value') It takes the initial string you want to convert as a parameter and returns the integer equivalent of the value you passed. The int() function in Python is used to cast a string to an integer data type. This section will focus on how to convert a Python string to an integer in a clear and concise manner. In Python, converting a string to an integer data type is a common task and can be easily achieved using several functions. Is it possible to convert a list of strings to a list of integers in Python?.
