Python String Method – startswith()

startswith() method –

The startswith method returns True if a string starts with a specified sub string otherwise it returns False.

string.startswith(prefix, start, end)

prefix – the sub string or a tuple that needs to be checked

start – start index from where the search starts

end – the end index where the search ends

In [2]: string.startswith('India')
Out[2]: True

In [3]: string.startswith('India is')
Out[3]: True

In [4]: string.startswith('great')
Out[4]: False

Startswith using the start and end parameters –

In [5]: string.startswith('is', 6, 15)
Out[5]: True

In [6]: string.startswith('is', 9, 15)

Startswith using a tuple –

You can also pass a tuple of prefixes. If the string starts with any of the prefixes then python returns True otherwise returns False.
