Python EOL (End Of Line)

Introduction

An EOL (End Of Line) is defined as a syntax error that indicates that the Python interpreter reached at the end of the line when it tried to scan a string literal. This is due to the missing quotes and strings spanning multiple lines.

The string literals need to be enclosed with a single quote or double quote. they can also be enclosed in matching groups of three single quotes.

Example:

s = "This is a string literal...

# Printing the string 

print(s)

Output:

File "EOL.py", line 2

    s = "This is a string literal...

                                   ^

SyntaxError: EOL while scanning string literal

The last character of the string is pointed by the small arrow and indicates that the error has occurred during defining that element of the statement.

String spanning Multiple Lines

Add definition or somekind of explanation.

Example -

def printMsg():

    str = "This is

      a test"

    print(str)

printMsg()

Output:

File "sample.py", line 2

str = "This is

SyntaxError: EOL while scanning string literal

Explanation –

In the above output, the error has occurred because the multiple lines can not be spanned by the string enclosed in single or double quotes. In Python, a multiple-line string starts and ends with three single quotes or three double-quotes.

Now, we will see how it actually works with the three single quotes and three double quotes.

Example:

def printMsg():

    str = """This is

      a string"""

    print(str)

printMsg()

Output:

This is

      a string

Fixing “Syntax Error: EOL while scanning string literal”

We can fix these syntax errors with the help of some solutions. These solutions are based on some common error-raising situations while the execution of a code.

There are four common situations where this error can be faced:

Placing the ending quotation mark

As we know that the syntax error is raised by the Python interpreter when the quotation mark is missing at the end of the string literal.

This error can be removed by placing the ending quotation marks.

Problem

#ending quotation mark is missing

string = "This is a string literal...

# Printing the string 

print(string)

Solution:

# Placing the ending quotation mark

string = "This is a string literal..."

# Printing the string 

print(string)

Output:

This is a string literal...

Matching the Quotation Marks

String literal enclosing can be done with the use of ' ' and " " in Python. If the quotation is incorrect at the ending of the string it will raise an error.

Problem:

# ending quotation mark is incorrect

string = "This is a string literal...'




# Printing the string 

print(string)

Solution:

# Matching the quotation marks

string = "This is a string literal..."


# Printing the string 

print(string)

Output:

This is a string literal...

Using the escape sequences \n

The effect of the new line is provided by the escape sequence '\n' to the string literal.

Problem:

# String dividing to multiple lines

string = "This is a string literal...

          Going to the next line"


# Printing the string 

print(string)

Solution:

# with escape sequences \n 

string = "This is a string literal... \n this is the next line"




# Printing the string 

print(string)

Output:

This is a string literal...

this is the next line

Using backslash before ending quotation mark

The backslash '\' can raise a syntax error and it is accountable for escaping the string. The solution to this problem can be removed by replacing the '\' backslash with an escape sequence for a (\\) backslash.

Problem:

# setting the directory path  

string = "\home\User\Desktop\"


# Printing the string 

print(string)

Solution:

# setting the directory path 

string = "\\home\\User\\Desktop\\"

# Printing the string 

print(string)

Conclusion

In the above article, we have learned how to remove the error EOL while scanning string literal and we have seen the solution to some common problems.
