How Can I Convert Comma-Separated Strings to Numbers in Python?

Converting Comma-Separated Strings to Numbers in Python

When encountering a string representing a number with commas inserted as thousand separators, converting it to a numeric value can present a challenge. Attempting to cast the string directly to an integer using int() will result in a ValueError.

Instead of manually removing the commas, a more elegant solution is to use the locale module in Python. By setting the locale to an English-based format, the locale module enables numbers to be parsed appropriately.

To demonstrate, import the locale module and set the locale to en_US.UTF-8:

import locale
locale.setlocale( locale.LC_ALL, 'en_US.UTF-8' ) 

Once the locale is set, the locale.atoi() and locale.atof() functions can be utilized to convert comma-separated strings to integers and floating-point numbers, respectively:

locale.atoi('1,000,000')
# 1000000

locale.atof('1,000,000.53')
# 1000000.53

By leveraging the locale module, you can effortlessly convert strings with comma-separated thousands separators to numeric values in Python, without interfering with the original string.
