Is there a way to substring a string in Python?

Question

Is there a way to substring a string in Python, to get a new string from the 3rd character to the end of the string?

Maybe like myString[2:end]?

EDIT: If leaving the second part means 'till the end', if you leave the first part, does it start from the start?

Answer 1

>>> x = "Hello World!"
>>> x[2:]
'llo World!'
>>> x[:2]
'He'
>>> x[:-2]
'Hello Worl'
>>> x[-2:]
'd!'

Answer 2

Yes there is. Your example is very close:

myString[2:]

Answer 3

myString[2:] .. leave off the second index to go to the end

Answer 4

mystring[2:]

Answer 5

You've got it right there except for "end". Its called slice notation. Your example should read.

new_sub_string = myString[2:]

If you leave out the second param it is implicitly the end of the string.

Answer 6

Besides the direct answer that others have given, you can find all the other rules for slicing behavior explained in the Strings section of the official tutorial.

Answer 7

One example seems to be missing here: full (shallow) copy.

>>> x = "Hello World!"
>>> x
'Hello World!'
>>> x[:]
'Hello World!'
>>> x==x[:]
True
>>>

This is a common idiom for creating a copy of sequence types (not of interned strings). [:] Shallow copies a list, See python-list-slice-used-for-no-obvious-reason.
