Escape characters are characters that are typically used to perform a specific task, and their use in your code instructs the compiler to take the appropriate action against these characters.

Example :

'\n'  -->  Leaves a line
'\t'  -->  Leaves a space 

# Python code to demonstrate escape character
# string

ch = "I\nLove\tGeeksforgeeks"

print ("The string after resolving escape character is : ")
print (ch)

Output :

The string after resolving escape character is : 
I
Love    Geeksforgeeks

But in certain cases it is desired not to resolve escapes, i.e the entire unresolved string has
to be printed. These are achieved by following ways.

# Python code to demonstrate printing
# escape characters from repr()

# initializing target string
ch = "I\nLove\tGeeksforgeeks"

print ("The string without repr() is : ")
print (ch)

print ("\r")

print ("The string after using repr() is : ")
print (repr(ch))

Output :

The string without repr() is : 
I
Love    Geeksforgeeks


The string after using repr() is : 
'I\nLove\tGeeksforgeeks'

Using “r/R”

Adding “r” or “R” to the target string triggers a repr() to the string internally and stops from the resolution of escape characters.

# Python code to demonstrate printing
# escape characters from "r" or "R"

# initializing target string
ch = "I\nLove\tGeeksforgeeks"

print ("The string without r / R is : ")
print (ch)

print ("\r")

# using "r" to prevent resolution
ch1 = r"I\nLove\tGeeksforgeeks"

print ("The string after using r is : ")
print (ch1)

print ("\r")

# using "R" to prevent resolution
ch2 = R"I\nLove\tGeeksforgeeks"

print ("The string after using R is : ")
print (ch2)

Output :

The string without r/R is : 
I
Love    Geeksforgeeks


The string after using r is : 
I\nLove\tGeeksforgeeks


The string after using R is : 
I\nLove\tGeeksforgeeks
