[solved] SyntaxError: unexpected EOF while parsing

The Syntax error: unexpected EOF while parsing error means your code has reached the end block and you forgot to close the block of code due to which the code didn’t compile all the block codes.

When your python code doesn’t form a meaningful structure, mistakes in syntax or in a code block. At that moment this error will pop up, and your python source code doesn’t run as per your expectations.

The most common reason for this error is;

• Your python block codes a for loop, a while loop, or a function are not properly enclosed.
• Your Python code block does not have enough parentheses.

In python, a code block begins with a statement that follows the next code block.

For example, for i in range (100): , this loop should give a proper statement in the upcoming block code in order to execute the program. Add Print(hello world)

Another reason for this error is when you don’t have enough parenthesis, or mistakenly wrote more than the required parentheses. Although you can handle this exception, using exception handling is a good practice.

You can below see some example errors related to this. Along with mentioned solutions for each so you can have a clear viewpoint to pull this off.

fixing SyntaxError: Unexpected EOF While Parsing for Loop function

In python the functions like For loops, if statements, and while loops, demand a  special statement next to them in order to execute them, in case you miss the value all code will raise the error.

For example- Look at this Python code,  we have defined a for loop containing the best programming language for cyber security, where the “Languages” is our variable storing the list of data that we have put.

program

Languages = ["Java", "SQL", "Python", "Javascript", "C++"]
for i in Languages:

When trying to execute this code block, it will end up with this error, which means there are some missing components, that python could fetch before the code reaches its end.

Output – Error

   
File "/Users/ssiddique/code/test.py", line 3
    
                       ^
SyntaxError: unexpected EOF while parsing

Solution

To fix this error we use the Print statement after this for loop, it will print each name given in the list without raising the error.

Languages = ["Java", "SQL", "Python", "Javascript", "C++"]
for i in Languages:
    print (i)

And this time the code will be executed without interfering with any error.

working – Output

Java
SQL
Python
Javascript
C++

It is all about missing a component in a code block, here is another example.

Fixing SyntaxError: Unexpected EOF While Parsing for python comment.

As the error is caused by a missing component, you can see the below Python code.

When executing this code we get the same error again.

program

language1 = "Python"
language2= "Java"
language3= "SQL."
print(" {} is better than these two {}. and {}".format(language1, language2, language3)

Output – error

  
File "/Users/siddique/code/test.py", line 5
    
                                                                                                       ^
SyntaxError: unexpected EOF while parsing

Solution

If you have noticed the code, we have opened the print statement but didn’t close, if we do then the code will turn out into something like this.

language1 = "Python"
language2= "Java"
language3= "SQL."
print("The {} is better than these two {}. and {}".format(language1, language2, language3))

It will work now since we have added at the last ) for the Print statement in order to close it.

Therefore the code has been completed and it will outcome as per our given statement.

working – Output

The Python is better than these two Java. and SQL.
