What is an Indentation Error?

An indentation error in Python is caused when the indentation of a code block is not consistent.Indentation is how Python knows what code should be executed together.If you get an error that says “Expected an indented block”, it means that there is a line of code that is not properly indented.

How to Fix an Indentation Error?

An indentation error in Python is caused when the compiler is unable to detect the proper indentation of a line of code. This usually happens when the programmer has forgotten to add a step in their code, or has accidentally deleted one.

Examples of Indentation Errors

Indentation is critical in Python. If a line of code is not indented properly, it will not run. The most common indentation error is due to forgetting to indent code that should be run together. Other indentation errors can be caused by accidentally mixing tabs and spaces when indenting code.

For example, the following code will not run because the second line is not indented properly:

print(“This line will print”)
print(“This line will not print”)

To fix this, we need to indent the second line so that it lines up with the first:

print(“This line will print”)
print(“This line will not print”)

Another common indentation error is caused by forgetting to dedent code that should not be run together. For example, the following code will not run because the third line is not dedented properly:

def some_function():
print(“This function has started”)
print(“This function is still going”)
print(“This function has ended”)

In this case, we need to dedent the third line so that it is no longer indented with the rest of the code in the function:
def some_function():
print(“This function has started”)

print(“This function has ended”)

Conclusion

In conclusion, an indentation error in Python is simply when your code is not properly indented. Indentation is crucial in Python, as it defines blocks of code. In most cases, you will receive an IndentationError when you have forgotten to indent something, or have incorrectly indented something.
