Reading python docs I have come to .isdecimal() and .isdigit() string functions and i'm not finding literature too clear on their usable distinction. Could someone supply me with code examples of where these two functions differentiate please.
Similar behaviour:
>>> str.isdecimal('1') True >>> str.isdigit('1') True >>> str.isdecimal('1.0') False >>> str.isdigit('1.0') False >>> str.isdecimal('1/2') False >>> str.isdigit('1/2') False

isdecimal() vs isdigit() vs isnumeric()isdecimal() method supports only Decimal Numbers. isdigit() method supports Decimals, Subscripts, Superscripts. isnumeric() method supports Digits, Vulgar Fractions, Subscripts, Superscripts, Roman Numerals, Currency Numerators.
The Python isnumeric method has a number of key differences between the Python isdigit method. While the isidigit method checks whether the string contains only digits, the isnumeric method checks whether all the characters are numeric.
Digits include decimal characters and digits that need special handling, such as the compatibility superscript digits. This covers digits which cannot be used to form numbers in base 10, like the Kharosthi numbers. Formally, a digit is a character that has the property value Numeric_Type=Digit or Numeric_Type=Decimal.
isdigit only returns True for what I said before, strings containing solely the digits 0-9.
There are differences, but they're somewhat rare*. It mainly crops up with various unicode characters, such as 2:
>>> c = '\u00B2' >>> c.isdecimal() False >>> c.isdigit() True You can also go further down the careful-unicode-distinction rabbit hole with the isnumeric method:
>>> c = '\u00BD' # ½ >>> c.isdecimal() False >>> c.isdigit() False >>> c.isnumeric() True *At least, I've never encountered production code that needs to distinguish between strings that contain different types of these exceptional situations, but surely use cases exist somewhere.
