Difference between isdigit(), isnumeric() and isdecimal()
In Python, the isdigit(), isnumeric(), and isdecimal() methods are used to determine whether a string contains only numeric characters. Although they may appear similar, each method has its own unique characteristics and purpose. Let’s Explore in depth the between these methods:
Difference between isdigit() and isdecimal()
In Python, isdigit() is a method of the str class and returns True if all characters in the string are numeric digits (0 to 9). Here, Python String isdecimal() returns False because not all characters in the “expr” are decimal.
Python3
expr = "4²"print("expr isdigit()?", expr.isdigit())print("expr isdecimal()?", expr.isdecimal()) |
Output
expr isdigit()? True
expr isdecimal()? False
Difference between isnumeric() and isdecimal()
In Python, isnumeric() is also a method of the str class, and it returns True if all characters in the string are numeric. Here, Python String isdecimal() returns False because not all characters in the “expr” are decimal.
Python3
expr = "⅔"print("expr isnumeric()?", expr.isnumeric())print("expr isdecimal()?", expr.isdecimal()) |
Output
expr isnumeric()? True
expr isdecimal()? False
Python string isdecimal() Method
Python String isdecimal() function returns true if all characters in a string are decimal, else it returns False. In this article, we will explore further the isdecimal() method, understand its functionality, and explore its practical applications in Python programming.
