Answer:
- \' is used to escape a single quote in a string enclosed in single quotes like;
my_string = 'this is John\'s ball'.
- \n is used to jump to a new line, Eg;
my_string = "Johns is a good boy\nbut he hates going to school."
the next set of the string after the '\n' character is displayed on the next line.
- \t is used to add a tab space to a string.
my_string = 'Jane is \thungry'
the character adds four character spaces before the word 'hungry'.
- \r adds a carriage return (or enter in keyboards) to start a new block paragraph in a string.
my_string = "Johns is a good boy\rbut he hates going to school."
Explanation:
Escape sequences in programming are used to format strings or output syntax of a program. They always begin with the backslash. Examples of escape sequence are " \' ", "\n", "\t", "\r", etc.
