Python string | digits Last Updated : 31 Dec, 2024 Summarize Comments Improve Suggest changes Share Like Article Like Report In Python, the string.digits constant contains all the digits from '0' to '9'. This can be very helpful when we need to work with numbers in string form. The string.digit will give the digits '0123456789'.Let's see how to use strings.digit: Python import string # Using string.digits dig = string.digits print(dig) Output0123456789 Example 1: Detecting and Extracting Numbers from Mixed StringIn many applications, we may need to detect and extract all numbers from a mixed string, such as extracting all the order numbers or item quantities from a report. Using string.digits, we can easily separate numbers from text. Python import string # Mixed string with numbers and text report = "Order #45: 12 items, Order #46: 7 items" # Extract all numbers using list comprehension n = ''.join([ch for ch in report if ch in string.digits]) print(n) Output4512467 Example 2: Generating a Random OTP (One-Time Password)In security applications, generating a one-time password (OTP) is a common task. Using string.digits, we can easily create a secure, random OTP by selecting digits from the string constant. Python import string import random # Generate a 6-digit OTP otp = ''.join(random.choices(string.digits, k=6)) print(otp) Output262856 Comment More infoAdvertise with us Next Article Python string isdecimal() Method S Shivam_k Follow Improve Article Tags : Python python-string Practice Tags : python Similar Reads string.octdigits in Python In Python, string.octdigits is a pre-initialized string constant that contains all valid characters for an octal number system. This includes the digits from 0 to 7, which are used in the representation of numbers in base 8.Let's understand how to use string.octdigits in Python:Python# import string 2 min read Python String isdigit() Method The isdigit() method is a built-in Python function that checks if all characters in a string are digits. This method returns True if each character in the string is a numeric digit (0-9) and False otherwise. Example:Pythona = "12345" print(a.isdigit()) b = "1234a5" print(b.isdigit())OutputTrue False 3 min read Python string isdecimal() Method In Python, the isdecimal() method is a quick and easy way to check if a string contains only decimal digits. It works by returning True when the string consists of digits from 0 to 9 and False otherwise. This method is especially useful when we want to ensure that user inputs or string data are stri 3 min read Convert String to Int in Python In Python, converting a string to an integer is important for performing mathematical operations, processing user input and efficiently handling data.
