How to Fix Unexpected EOF While Parsing Error In Python

59

In this tutorial, you will learn how fix unexpected EOF while parsing error in Python. Unexpected EOF while parsing error is a Syntax error and occurs when the interpreter reaches the end of the python code before any code block is complete. This error occurs when the body is not coded/included inside conditional statements (if, else), loops (for, while), functions, etc.

Below are the cases when the “Unexpected EOF While Parsing Error” occurs and also provided the ways to fix those errors.

How to Fix Unexpected EOF While Parsing Error In Python

how to fix unexpected eof while parsing error in python

1. Fix – Unexpected EOF while parsing error when using conditional statements

Unexpected EOF while parsing error occurs in conditional statements when any if, else statement is used without a single line of the body.

Example 1: Let’s look into the sample code which throws the Unexpected EOF error while using the if statement.

Code:

number = 1
if(number==1):

Error:

File "<ipython-input-2-8cb60fd8f815>", line 2
    if(number==1):
                  ^
SyntaxError: unexpected EOF while parsing

2. Fix – Unexpected EOF while parsing error when using loops

Unexpected EOF while parsing error occurs in loops when any for/while statement is used without a single line of body inside them.

Example 1: Let’s look into the sample code that throws the Unexpected EOF error while using the loop.

sum=0
# sum of 1-10 numbers
for i in range(1,11):

Error
File "<ipython-input-7-1f8b5a6d6ae0>", line 3
    for i in range(1,11):
                         ^
SyntaxError: unexpected EOF while parsing

The error unexpected EOF while parsing occurred because the for loop didn’t consist of a body/code to execute inside the loop. So to fix this error, we need to add the code block inside the for loop.

Code Fix:

sum=0
# sum of 1-10 numbers
for i in range(1,11):
    sum=sum+i
print("Sum of 1-10 numbers = ",sum)

Output:

Sum of 1-10 numbers =  55

Example 2: Let’s look into the sample code which throws the Unexpected EOF error while using a while loop.

Code:

number=1
# print 1 to 10 number
while(i<=10):

Error:

File "<ipython-input-10-f825e1f8a55a>", line 3
    while(i<=10):
                 ^
SyntaxError: unexpected EOF while parsing

The error unexpected EOF while parsing occurred because the while loop didn’t consist of a body/code to execute. So to fix this error, we need to add the code block inside the while loop.

# print 1 to 10 number
while(number<=10):
    print(number,end=" ")
    number=number+1

Output:

3. Fix – Unexpected EOF while parsing error in functions

Unexpected EOF while parsing error occurs in function when any function is defined without a body or when we made syntax mistakes while calling the function.

Example 1: Let’s look into the sample code which throws the Unexpected EOF error when we define any function with no body.

Code:

def findEvenorNot(number):

Error:

File "<ipython-input-17-7cb37f6aa589>", line 1
    def findEvenorNot(number):
                              ^
SyntaxError: unexpected EOF while parsing

The error unexpected EOF while parsing occurred because the function findEvenorNot is defined without anybody/code. So to fix this error, we need to add the code block inside the function.

Code Fix:

def findEvenorNot(number):
    if(number%2==0):
        print(number," is Even")
    else:
        print(number," is Odd")
        
findEvenorNot(24)

Output:

24 is Even

Example 2: Let’s look into another sample code that throws the Unexpected EOF error when we call a function with incorrect syntax.

Code:

def findEvenorNot(number):
    if(number%2==0):
        print(number," is Even")
    else:
        print(number," is Odd")
        
findEvenorNot(

Error:

File "<ipython-input-24-35123bc59f61>", line 7
    findEvenorNot(
                  ^
SyntaxError: unexpected EOF while parsing

The error unexpected EOF while parsing occurred because the function call had incorrect syntax. So to fix this error, we need to call the function with proper syntax i.e., functionName(parameter1, parameter2, …..).

Code Fix:

    if(number%2==0):
        print(number," is Even")
    else:
        print(number," is Odd")
        
findEvenorNot(831)

Output:

831  is Odd

4. Fix – Unexpected EOF while parsing error due to missing parenthesis

Unexpected EOF while parsing error also occurs if we miss any parentheses while using any standard/user-defined functions.

Note: The above example also comes under this category.

Example: Let’s look into an example code that throws the Unexpected EOF error due to missing parenthesis.

Code:

programmingLanguages=["C", "C++","Java","Python","JS"]

for lang in programmingLanguages:
    print(lang

Error:

File "<ipython-input-27-c9c853e4f9e6>", line 4
    print(lang
              ^
SyntaxError: unexpected EOF while parsing

The error unexpected EOF while parsing occurred due to closing parenthesis miss in the print statement. So to fix this error, we need to add the missing parenthesis.

Code Fix:

programmingLanguages=["C", "C++","Java","Python","JS"]

for lang in programmingLanguages:
    print(lang)

Output:

C

C++

Java

Python

JS

5. Fix – Unexpected EOF while parsing error in Try Except blocks

Unexpected EOF while parsing error also occurs if we didn’t include an except block for a try block.

Example: Let’s look into an example code that throws the Unexpected EOF error due to missing an except block for a try block.

Code:

number = 18

try:
    result = number/0
    print(result)

Error:

File "<ipython-input-2-79e117053f09>", line 5
    print(result)
                 ^
SyntaxError: unexpected EOF while parsing

The error unexpected EOF while parsing occurred due to the absence of except block for a try block. So to fix this error, we need to include an except block for the try block.

Code Fix:

number = 18

try:
    result = number/0
    print(result)
    
except:
    print("Division by zero exception")

Output:

Division by zero exception
