Python Built-in Functions

Python provides us with many built-in functions that can be used directly without importing any modules. These functions can be used for various tasks such as mathematical operations, type conversions, I/O operations, etc.

Syntax

The syntax for using a built-in function in Python is as follows:

function_name(arguments)

Example

Here's an example of using the built-in function len() to find the length of a string:

str = "Hello, World!"
print(len(str))

Output

13

Explanation

In the above example, we have used the len() function to find the length of the string str. The len() function returns the number of elements in the object.

Use

Python built-in functions can be used for various tasks such as:

• Mathematical operations: abs(), pow(), round()
• Type conversions: int(), float(), str()
• I/O operations: input(), print()
• List operations: max(), min(), sorted()
• And many more

Important Points

• Built-in functions in Python can be used directly without importing any modules.
• There are many built-in functions available in Python for a variety of tasks.
• Built-in functions are very helpful in reducing the amount of time and effort required for coding.

Summary

In this tutorial, we have learned about built-in functions in Python and their syntax, examples, output, explanation, use cases, and important points to remember. Python built-in functions are very useful for performing various tasks and can save a lot of time and effort in coding.
