Hmm. Throw in a paperclip and we'd have an episode of MacGyver. UpdateI know that this has been closed out as a duplicate, but here's a method that works for both Python 2 and Python 3:
In this article, we will learn to delete numerical values from a given string in Python. We will use some built-in functions and some custom codes as well. Let's first have a quick look over what is a string in Python. Python StringThe string is a type in python language just like integer, float, boolean, etc. Data surrounded by single quotes or double quotes are said to be a string. A string is also known as a sequence of characters.
A string in Python can contain numbers, characters, special characters, spaces, commas, etc. We will learn four different ways to remove numbers from a string and will print a new modified string. Example: Remove Numbers from String using regexPython provides a regex module that has a built-in function In the below example, we take a pattern as r'[0-9]’ and an empty string as a replacement string. This pattern matches with all the numbers in the given string and the sub() function replaces all the matched digits with an empty string. It then deletes all the matched numbers.
Example: Remove Numbers from String using join() & isdigit()This method uses The below example skips all numbers from the string while iterating and joins all remaining characters to print a new string.
Example: Remove Numbers from String using translate()This method uses The below example creates a translation table and replaces characters in string based on this table, so it will delete all numbers from the string
Example: Remove Numbers from StringThis example uses the filter() and lambda in the generating expression. It filters or deletes all the numbers from the given string and joins the remaining characters of the string to create a new string. The filter() function uses the original string and lambda expression as its arguments. First, we filtered all digit characters from a string and then joined all the remaining characters.
ConclusionIn this article, we learned to remove numerical values
from the given string of characters. We used different built-in functions such as How do I remove a number from a string in Python?Let's discuss the different ways we can achieve this task.. Method #1: Using join and isdigit(). Method #2: Using translate and digits.. Method #3: Using filter and lambda.. Method#4 Using join() and isalpha(). Method#5: Using loop and in.. Method #6: Using ord() function.. How do you strip a value in Python?The strip() method in-built function of Python is used to remove all the leading and trailing spaces from a string. Parameter: chars(optional): Character or a set of characters, that needs to be removed from the string. Returns: A copy of the string with both leading and trailing characters stripped.
