For a long time,Python has been a very well-liked programming language. This is primarily because of its adaptability and simple syntax. Python can be used in almost any area of software development.
We are assuming that you must have written some amazing codes in python. But, have you ever encountered an Indentation error in your code?
This article will guide you through the syntaxerror return outside function in python. Also, it will clear all your doubts regarding the same.
So, let us start understanding the syntaxerror return outside function:
SyntaxError Return Outside Function
Errors are problems that occur in a code because of an illegal operation performed by the user or a programming error that halts the normal flow of the program. Errors are also known as bugs or faults.
In Python programming, there are two types of errors.
Syntax Error
Logical Error
In this article, we will be looking for SyntaxError Return Outside Function.
A syntax error is one of the most fundamental types of programming errors. The syntax error simply indicates that the Python parser is unable to understand a line of code. When we do not write the proper syntax of the Python programming language (or any other language), the Python interpreter throws a syntax error.
Let us take an example to find whether a number is even or odd:
Python
Python
number = 89 if number&1 == 0 print("Number is even") else: print("Number is odd")

# Function to return the result of multiplication of two numbers def func(a, b): # Print the value of a*b mul = a * b return(mul) # Print values in list print('Multiplication: ', func(10, 34));

Return Outside Function Python SyntaxError Due to Indentation
In Python, a return statement must be inside the body of a function. If a return statement is encountered outside a function, Python will raise a SyntaxError because it expects the statement to be within the scope of a function. This error occurs due to incorrect indentation.
Here's a brief explanation:
Return Statement: The return statement is used in Python to exit a function and return a value to the caller.
Inside Function Body: A return statement should be indented to the same level as other statements within the function body.
Outside Function Body: Placing a return statement outside any function's body results in a SyntaxError because Python doesn't understand where it should return to.
For example:
def my_function():
result = 10
# Inside the function body, correct indentation
return result
print(my_function())
In the example, return is correctly used within the function my_function(), but it's wrongly placed outside the function. Python expects all executable code to be within function definitions or appropriately scoped blocks.
Return Value Outside Function Due to Looping
This error can occur if you mistakenly place a return statement within a loop outside of any function. For example:
for item in some_list:
# Some condition
return item # This will raise an error
Ensure that your return statement is within a function. If you intend to return a value from within a loop, you should first collect the values within the loop and then return them outside of the loop, within the function scope.
Here's an example illustrating this:
def process_list(some_list):
result = []
for item in some_list:
result.append(item)
return result
my_list = [1, 2, 3, 4, 5]
processed_list = process_list(my_list)
print(processed_list)
This code will throw an error:
File "<string>", line 5
SyntaxError: 'return' outside function
So, to fix this we need to take care of the return statement:
Python
Python
def process_list(some_list): result = [] for item in some_list: result.append(item) return result
This code collects items from some_list based on certain conditions and returns them as a list. Ensure that your return statements are properly structured within functions and not placed outside of them or within loops without being inside a function.
