The `insert()` function in Python is used to insert an element at a specific position in a list. The syntax for the `insert()` function is: list.insert(index, element) index: The position where the element has to be inserted. element: The element that needs to be inserted into the list. Example: # Create a list my_list = […]

The `extend()` function in Python is used to add multiple items from an iterable (like a list, tuple, or string) to the end of an existing list. It essentially extends the list by appending elements from the given iterable. Syntax: list.extend(iterable) – `list`: The list that will be extended. – `iterable`: The iterable whose items […]

The `append()` function in Python is used to add an element to the end of a list. It modifies the original list by adding the new element. Syntax: list.append(element) list: The list you want to add an element to. element: The element you want to add to the list. Example: # Create a list my_list […]

The `decode()` function in Python is used to convert bytes into a string. This function is often used when you have data in bytes format (like from a file or a network socket) and you want to convert it into a human-readable string. Basic Syntax bytes.decode(encoding=’utf-8′, errors=’strict’) Here’s an example: Example: Suppose you have a […]

The `encode()` function in Python is used to convert a string into a specified encoding format. This function returns the encoded version of the string as a bytes object. It’s commonly used when dealing with text data that needs to be converted to bytes for storage or transmission. Syntax string.encode(encoding=’utf-8′, errors=’strict’) encoding: The encoding format […]

The `format()` function in Python is used for string formatting. It allows you to embed values into a string in a flexible way. Basic Usage Here’s a simple example of using `format()`: name = “Alice” age = 30 formatted_string = “My name is {} and I am {} years old.”.format(name, age) print(formatted_string) Output: My name […]

The `isspace()` function in Python is a string method that checks whether all the characters in a given string are whitespace characters. If the string contains only whitespace characters and is not empty, it returns `True`. Otherwise, it returns `False`. Syntax string.isspace() Example Usage Here are a few examples demonstrating the use of the `isspace()` […]

The `isalpha()` function in Python is a string method used to check whether all the characters in a given string are alphabetic (letters only). It returns `True` if all characters in the string are alphabetic and the string is non-empty, otherwise it returns `False`. Syntax string.isalpha() Example Here’s an example to demonstrate the usage of […]

The `isdigit()` function in Python is a string method that checks if all the characters in a string are digits. It returns `True` if all characters are digits and there is at least one character, otherwise it returns `False`. Syntax string.isdigit() Example Here’s an example to demonstrate how to use the `isdigit()` function: “`python # […]

The `endswith()` method in Python is used to check if a string ends with a specified suffix. It returns `True` if the string ends with the suffix, and `False` otherwise. You can also specify a start and end position to limit the check to a substring. Syntax str.endswith(suffix[, start[, end]]) – suffix: The suffix to […]

The `startswith()` method in Python is used to check if a string starts with a specified prefix. It returns `True` if the string starts with the prefix, otherwise it returns `False`. Syntax str.startswith(prefix[, start[, end]]) – prefix: The prefix or tuple of prefixes to check for. – start (optional): The position in the string to […]

The `count()` function in Python is used in different contexts depending on whether you are working with a list, tuple, string, or other iterable. It is used to count the number of occurrences of a specific element in the iterable. Syntax For a list, tuple, or string: iterable.count(value) – iterable: The list, tuple, or string […]

The `find()` function in Python is a string method used to search for the first occurrence of a specified substring within another string. It returns the index of the first character of the substring if found; otherwise, it returns `-1`. Syntax string.find(substring, start, end) – substring: The string to be searched within the main string. […]

The `join()` function in Python is used to concatenate the elements of an iterable (like a list or tuple) into a single string. The elements are joined together using a specified separator. Syntax separator_string.join(iterable) – separator_string: The string that will be placed between each element of the iterable. – iterable: The iterable containing strings to […]

The `split()` function in Python is used to split a string into a list of substrings based on a specified delimiter. By default, it splits the string at each whitespace. Syntax string.split(separator, maxsplit) – separator (optional): The delimiter at which to split the string. If not provided, the string is split at any whitespace (space, […]

The `replace()` function in Python is used to replace occurrences of a specified substring within a string with another substring. This function does not modify the original string but returns a new string with the replacements. Syntax str.replace(old, new, count) `old`: The substring you want to replace. `new`: The substring that will replace the old […]

The `strip()` function in Python is used to remove any leading (spaces at the beginning) and trailing (spaces at the end) characters (by default, it removes whitespace characters) from a string. Syntax string.strip([chars]) string: The original string on which the `strip()` function is applied. chars(optional): A string specifying the set of characters to be removed. […]

The `lower()` function in Python is used to convert all the characters in a string to lowercase. It returns a new string with all characters converted to lowercase. Syntax string.lower() string: The string you want to convert to lowercase. Example # Original string original_string = “Hello, WORLD!” # Convert to lowercase lowercase_string = original_string.lower() print(“Original […]

The `upper()` function in Python is a string method used to convert all lowercase characters in a string to uppercase. It doesn’t modify the original string but returns a new string with all characters converted to uppercase. Syntax string.upper() Example Here’s a simple example to illustrate the use of the `upper()` function: # Original string […]

The `capitalize()` function in Python is used to convert the first character of a string to uppercase and all other characters to lowercase. Syntax string.capitalize() string: The string you want to capitalize. Example text = “hello world!” # Using capitalize() function capitalized_text = text.capitalize() print(capitalized_text) Output Hello world! Explanation – In the example above, the […]

In Python, there isn’t a built-in `factorial()` function directly available in the base language, but you can find it in the `math` module. Here’s how you can use it: Using the `math.factorial()` Function The `math.factorial()` function computes the factorial of a given non-negative integer. Syntax import math result = math.factorial(x) – x: A non-negative integer […]
