If the prefix string is not found, then it returns the original string.Example: Python s1 = 'Geeks'.removeprefix("Gee") print(s1) Output:ksLet's take a deeper look at removeprefix():Table of ContentSyntax:Example of removeprefix() methodPractical Applications of removeprefix()Syntax:string.removeprefix(prefix)Parameters:string: The original string from which the prefix will be removed.prefix: The substring you want to remove from the start of the string.Return Type: The method returns a new string with the specified prefix removed, if it exists. If the string does not start with the given prefix, it simply returns the original string.Example of removeprefix() methodWe can remove a prefix string from a string using Python String removeprefix() Method. If the prefix is not the prefix in the string, the original string is returned. Python # Basic Usage s = "HelloWorld" res = s.removeprefix("Hello") print(res) # Output: World # No Prefix Match s = "PythonProgramming" res = s.removeprefix("Java") print(res) # Output: PythonProgramming # Case Sensitivity s = "PythonProgramming" res = s.removeprefix("python") print(res) # Output: PythonProgramming Output:WorldPythonProgrammingPythonProgrammingExplanation:string "HelloWorld" has the prefix "Hello", so it removes it and returns "World".Since the string doesn't start with "Java", the original string is returned unchanged.The method is case-sensitive, so it does not remove "python" (lowercase) from "PythonProgramming" because the prefix "python" does not match the case of the actual string's prefix "Python".Practical Applications of removeprefix()Cleaning Data: When processing files or strings with standard prefixes (like file paths, URLs, or formatted strings), removeprefix() can be used to cleanly remove unwanted prefixes.Processing URLs: In web scraping or web applications, you may need to strip a common domain prefix or protocol (http://, https://) from URLs.Automating String Parsing: In scenarios where strings are prefixed with specific identifiers, such as command-line arguments or data fields, removeprefix() can be helpful to automate the parsing.Processing Version Numbers: If version numbers are prefixed with a specific string (e.g., "v" for versions), removeprefix() can be used to extract just the version number.Code Example: Python # Cleaning Data p1 = "/home/user/documents/file.txt" p2 = p1.removeprefix("/home/user/") print(p2) # Output: documents/file.txt # Removing URL Prefix url1 = "https://example.com" url2 = url.removeprefix("https://") print(url2) # Output: example.com # Parsing Command-Line Arguments c = "cmd-12345" id1 = "cmd-" id2 = c.removeprefix(id1) print(id2) # Output: 12345 # Removing Version Prefix v1 = "v1.2.3" v2 = v1.removeprefix("v") print(v2) # Output: 1.2.3 Output:documents/file.txtexample.com123451.2.3 Comment More infoAdvertise with us Next Article Python String - removeprefix() function M MuskanKalra1 Follow Improve Article Tags : Technical Scripter Python Technical Scripter 2020 Python-string-functions Practice Tags : python Similar Reads Python Tutorial - Learn Python Programming Language Python is one of the most popular programming languages.
