HOW TO FORMAT AND PARSE NUMBER
In Locale module we are given two specialized functions to parse a string into a number which is based on the current locale:
atof : it converts string into a floating point number which follows the LC_NUMERIC settings. Syntax for the following function is given below:
atof : it converts string into an integer number which follows the LC_NUMERIC convention. Syntax for the following function is given below:
It is extremely useful for parsing a string that has a comma or dot, as different locales interpret it differently. For example:
Here ,32,824 is 32824.00 for en_SG(English/SIngapore) and 32,824 is 32.824 for de_DE(German)
Further on, we can use the format_string() function to format a number according to your preferences. The following code is based on the de_DE locale:
locale.format_string('%10.2f', 738213.78, grouping=True)
We can set a grouping parameter for the format_string() function, which accepts a boolean(which is either True or False).
- grouping (if it is set to True, it takes grouping into account; or, it will be False by default).
