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: 
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.
As excellently answered by @Jimmy I further give the following examples to make the matter more clear.

Case 1:

```
>>> var1 = "Adolf Hitler was a German dictator. He started the second world war."
>>> print(var1)
Adolf Hitler was a German dictator. He started the second world war.
>>> 

```

Case 2:

```
>>> var2 = "Adolf Hitler\
...  was a German dictator.\
...  He started the\
...  second world war."\
... 
>>> print(var2)
Adolf Hitler was a German dictator. He started the second world war.
>>>

```

Case 3:

```
>>> var3 = "Adolf Hitler\nwas a German dictator.\nHe started the\nsecond world war."
>>> print(var3)
Adolf Hitler
was a German dictator.
He started the
second world war.
>>>

```

Case 4:

```
>>> var4 = "Adolf Hitler\
... \nwas a German dictator.\
... \nhe started the\
... \nsecond world war."\
... 
>>> print(var4)
Adolf Hitler
was a German dictator.
he started the
second world war.
>>>

```

There is also another point which @Jimmy has not mentioned. I have illustrated it by the following two examples -

Example 1:

```
>>> var5 = """
... This multi-line string
... has a space at the top
... and a space at the bottom
... when it prints.
... """
>>> print(var5)

This multi-line string
has a space at the top
and a space at the bottom
when it prints.

>>>

```

Example 2:

```
>>> var6 = """\
... This multi-line string
... has no space at the
... top or the bottom
... when it prints.\
... """
>>> print(var6)
This multi-line string
has no space at the
top or the bottom
when it prints.

```
