indentation in python

 In Python, indentation refers to the whitespace (spaces and/or tabs) at the beginning of a line of code. Unlike many other programming languages, which use curly braces or other symbols to mark the beginning and end of blocks of code, Python uses indentation to group statements together.

For example, here is a Python code block that uses indentation to group together three statements:

python
x = 5 
if x < 10: 
    print("x is less than 10") 
    print("This statement is also inside the if block.") 
print("This statement is outside the if block.")

In this example, the if statement is indented, so the two print statements are part of the block of code that is executed only if x is less than 10. The final print statement is not indented, so it is executed regardless of the value of x.

It's important to use consistent indentation throughout your Python code, typically with either spaces or tabs (not a mixture of both). Inconsistent indentation can lead to errors and make the code difficult to read and understand. The standard convention in Python is to use four spaces for each level of indentation.
