Does Python have a string contains substring method

Question

I want to do:

if not somestring.contains("blah"):
   continue

Answer 1

You can use in operator to access sub strings in Python.
in returns boolean value either True or False.

For Example:
statement = 'I am answering this question'
'I' in statement

Output

True

'not' in statement

Output

False

Another way is to use indexing str.find (which returns -1 on failure and returns the index position of the string on success )

start = 0
end = len(statement)
statement.find('not', start, end)

Output

-1

statement.find('I', start, end)

Output

0
