Python built in functions

Python's built-in functions are a collection of essential tools that simplify common programming tasks. They are pre-defined functions provided by Python's standard library, offering a wide range of functionalities for various purposes. These functions are readily available, eliminating the need to write code from scratch and saving you valuable time and effort.

Let's explore some of the most frequently used Python basic built-in functions and how they can supercharge your coding.


Python print() function - A Gateway to Output

The print() function is the most basic function in Python. It allows you to display text, variables, or results on the console, making it a crucial tool for debugging and monitoring your code. With print(), you can easily visualize the output of your program and ensure it's working as expected. read more

print("Hello, World!")


Python len() function - Measuring the Length

When you need to determine the length of a string, list, or any iterable, the len() function is used. It returns the number of elements within the object, providing valuable insights for data analysis and manipulation. learn how to use python len function in python

my_list = [1, 2, 3, 4, 5]

length = len(my_list)

print("Length of list is:", length)


Python input() function - Python User Interaction

Python is not limited to automated processes, it also excels in user interaction. The input() function enables you to receive input from users and adapt your program's behavior accordingly. It's a valuable function for creating interactive applications.

user_name = input("Please enter your name: ")

print("Hello, " + user_name + "!")


Python min() and max() functions - Finding Extremes

When working with data, it's essential to find the maximum and minimum values. Python's min() and max() functions allow you to identify the highest and lowest elements in a collection, which is important for data analysis and decision making.

data = [15, 42, 8, 97, 64]

minimum = min(data)

print("Minimum value:", minimum)

maximum = max(data)

print("Maximum value:", maximum)


Python range() function - Generating Sequences

Creating sequences of numbers is a common task in programming. Python's range() function simplifies this process by generating a sequence of numbers based on your specified parameters. It's particularly useful in for loops and list comprehensions.

for number in range(1, 7):

    print(number)


Python sorted() function - Made Sorting Simple

Sorting data is a fundamental operation in programming, and sorted() function does this task. It can sort a list or other iterable in ascending or descending order, allowing you to organize and access your data efficiently.

unsorted_list = [4, 2, 9, 1, 6]

sorted_list = sorted(unsorted_list)

print("Sorted list:", sorted_list)


Python sum() function - Adding It Up

For quick and accurate summation of elements within a list or iterable, there is a sum() function available in Python. It's an excellent choice for calculating totals, averages, and more.

numbers = [5, 20, 10, 15]

total = sum(numbers)

print("Total sum:", total)


Python type() function - Finding data type

type() function is used to determine the data type of a given object. It helps you understand whether an object is an integer, string, list, or any other data type, which is crucial for effective coding and data manipulation. 

x = 42

print(type(x))  # This will output <class 'int'>

x = "Python Mastery Hub"

print(type(x))  # This will output <class 'str'>

x = [3, 4.5, "Python"]

print(type(x))  # This will output <class 'list'>

len() Function Python

In the dynamic realm of programming, the ability to measure the length of data structures is fundamental. Python provides a powerful tool for this purpose – the len() function. Understanding Python len() function At its core, the len() function in Python is designed to provide the length of a given data structure. Whether you're working with strings, lists, tuples, or dictionaries, this function serves as a reliable metric to quantify the size of your data. Common use cases of len() function Let's explore some common scenarios where the  len()  function proves invaluable. Working with strings Strings, the building blocks of text in programming, can be effortlessly measured using  len() . It  returns the count of characters in the string.  Consider the following example: blog = "Python Mastery Hub" length = len(blog) print("Length of the string:", length) In this instance, it gives output:  Length of the string: 18   Lists and tuples Moving beyond str...

Loops in Python - Mastering While and For Loops

In this article, we'll learn Python loops, focusing on while and  for  loops, loop iteration, and loop control statements like  break ,  continue  and  pass Python loops are an essential part of its appeal. These loops enable you to perform repetitive tasks with ease, and mastering them is a fundamental step towards becoming a proficient Python programmer. Python while loop while  loops in Python are used when you want to execute a block of code as long as a specific condition remains true. They provide an elegant way to repeat tasks until a certain criterion is met. Look at the example below: count = 0 while count < 5:     print("Count:", count)     count += 1 In this example, the code inside the while loop will execute as long as the count variable is less than 5. Once  count  reaches 5, the loop terminates. Python for loop: for loops are perfect for iterating through sequences such as lists, strings, or other ...
