Question: I am coming from C language

In book of Python it is given

among escape sequence

\ - New line in a multi-line string

\n - Line break

I am confused and unable to differentiate between the two.

Answer: 
\ - New line in a multi-line string
-----------------------------------

It is used for splitting a string which has a vast number of characters into multi lines as it is inconvenient to write in a single line.
This is something that has effect in the code only.

\n - Line break
---------------

This one on the other hand is a typical line break statement for printing something in a new line. The same thing we use in C and C++ languages.
this is something that has effect in the output.
Use \n to have your output go to the next line.

```
print('Hello \nworld!')

```

> 
> Hello
> 
> 
> world!
> 
> 
> 

Use the back slash with a character that has a meaning to Python when you want that character to appear in the printed output.

```
print('It\'s cold outside')

```

> 
> It's cold outside
> 
> 
> 

I hope this helps.
