🔥 Python String Methods Cheat Sheet Python provides many built-in methods to manipulate strings easily. ✅ Common String Methods Method - lower() Description - Converts to lowercase Example - "HELLO".lower() → 'hello' ----------------------------------------------- Method - upper() Description - Converts to uppercase Example - "hello".upper() → 'HELLO' ----------------------------------------------- Method - capitalize() Description - Capitalizes first letter Example - "hello world".capitalize() → 'Hello world' ----------------------------------------------- Method - title() Description - Capitalizes first letter of every word Example - "hello world".title() → 'Hello World' ----------------------------------------------- Method - strip() Description - Removes whitespace from both sides Example - " hello ".strip() → 'hello' ----------------------------------------------- Method - replace(old, new) Description - Replaces substring Example - "hello".replace("l", "w") → 'hewwo' ----------------------------------------------- Method - split(separator) Description - Splits string into list Example - "hello world".split(" ") → ['hello', 'world'] ----------------------------------------------- Method - join(iterable) Description - Joins list into string Example - " ".join(['hello', 'world']) → 'hello world' ----------------------------------------------- Method - startswith(sub) Description - Checks if string starts with substring Example - "hello".startswith("he") → True ----------------------------------------------- Method - endswith(sub) Description - Checks if string ends with substring Example - "hello".endswith("lo") → True ----------------------------------------------- Method - find(sub) Description - Returns index of substring (if found) Example - "hello".find("e") → 1 ----------------------------------------------- Method - count(sub) Description - Counts occurrences of substring Example - "hello".count("l") → 2 ----------------------------------------------- Method - isalpha() Description - Checks if all characters are alphabets Example - "hello".isalpha() → True ----------------------------------------------- Method - isdigit() Description - Checks if all characters are digits Example - "123".isdigit() → True ----------------------------------------------- Method - isalnum() Description - Checks if all characters are alphanumeric Example - "hello123".isalnum() → True ----------------------------------------------- Method - islower() Description - Checks if all characters are lowercase Example - "hello".islower() → True ----------------------------------------------- Method - isupper() Description - Checks if all characters are uppercase Example - "HELLO".isupper() → True ----------------------------------------------- 🎯 Bonus Methods Method - zfill(width) Fills string with zeros from the left -----------------------------------------------' Method - swapcase() Swaps uppercase to lowercase and vice versa ----------------------------------------------- Method - rjust(width) Right-align string with spaces ----------------------------------------------- Method - ljust(width) Left-align string with spaces ----------------------------------------------- #Python #PythonProgramming #PythonDeveloper #PythonTutorial #LearnPython #PythonCoding #PythonCourse #PythonForBeginners #PythonScripts #PythonProjects #PythonTips #PythonTricks #PythonFullCourse #PythonAutomation #PythonWebDevelopment #PythonBackend #PythonAPIs #PythonStringMethods #PythonOOP #PythonLibraries #PythonWithAI #PythonChatGPT #PythonNextjs #PythonMachineLearning #PythonDjango #PythonFlask #PythonAutomationScripts #PythonAIProjects #PythonInterviewQuestions #PythonIn60Seconds #PythonShorts #PythonTipsAndTricks #PythonCodingChallenge #PythonForBeginners #PythonFromScratch #PythonBasicToAdvanced #PythonStepByStep #PythonInHindi #PythonCodingJourney

🔥 Important Python Functions Every Developer Should Know Here is a list of most important built-in Python functions that every developer must know 💪: ✅ Basic Functions Function Description print() =>Console output (data display) input() =>Take user input type() =>Check data type len() =>Count the number of elements id() =>Returns memory address of object ------------------------------------------ 🔢 Number Functions Function Description abs() =>Returns absolute value round() =>Round off the number pow() =>Power of a number pow(x,y) = x^y min() =>Minimum value max() =>Maximum value ------------------------------------------ 🔥 List Functions Function Description append() =>Add item at end insert() =>Add item at index remove() =>Remove specific item pop() =>Remove item from end sort() =>Sort list reverse() =>Reverse list ------------------------------------------ 🎯 String Functions Function Description lower() =>Convert to lowercase upper() =>Convert to uppercase strip() =>Remove whitespace replace() => Replace substring split() =>Split into list join() =>Join list into string ------------------------------------------ 🔑 Dictionary Functions Function Description keys() =>Returns all keys values() =>Returns all values items() =>Returns key-value pairs get() =>Get value by key pop() =>Remove item by key ------------------------------------------ 🌶️ Advanced Functions Function Description map() =>Apply function to all items filter() =>Filter elements based on condition lambda =>Anonymous function zip() =>Combine two lists enumerate() =>Add counter to list ------------------------------------------ 🧠 Important Built-in Functions Function Description isinstance() =>Check if object is instance of class sum() =>Sum of elements all() =>Check if all elements True any() =>Check if any element True sorted() =>Sort elements ------------------------------------------ 🔥 File Handling Functions Function Description open() =>Open file read() =>Read file content write() =>Write to file close() =>Close file ------------------------------------------ Bonus Tips 💪 zip() – Combine multiple lists into tuples map() – Apply a function on every element filter() – Filter elements based on condition enumerate() – Add counter to list items #Python #PythonTutorial #PythonProgramming #PythonCourse #PythonFullCourse #PythonInOneVideo #PythonProject #LearnPython #PythonForBeginners #PythonDeveloper #PythonProject2025 #PythonMiniProject #PythonFinalYearProject #PythonAI #PythonCRUD #PythonAI #PythonML #ChatbotWithPython #AIProjectPython #PythonOpenAI #javascript #PythonInHindi #PythonTutorialHindi #coder #PythonCourseFree #Python2025 #pushpendratips #PythonWithProjects
