lst1=['spot','mistake']
lst1_tweets=tweets[tweets['tweet_text'].str.contains('|'.join(lst1))].reset_index()
I want to double check and have:
f=lst1_tweets['tweet_text'][0]
f='Spot the spelling mistake Welsh and Walsh. You are showing picture of presenter Bradley Walsh who is alive and kick'
type(f)
<class 'str'>
I used
f.str.contains('|'.join(lst1))
returns:
AttributeError: 'str' object has no attribute 'str'
f.contains('|'.join(lst1))
returns:
AttributeError: 'str' object has no attribute 'contains'
Any suggestions how I can search for a list of words in a string
                You can only use .str.contains() on a Pandas series, not after extracting an individual string.

                Here your f is referencing a Python string, whose class is named str: type(f) is str. pandas.Series.str is a different class with different attributes, including contains. You can check if a class has an attribute by a certain name (without raising an Exception, that is) with the built-in callable hasattr

                This could be a problem because list of strings he's searching for contains 'spot' and 'mistake', but the string he's searching in contains 'Spot' and 'mistake'. Upper-case and lower-case characters are encoded differently, so the in operator for Python strings is case sensitive, and unlike pandas.Series.str.contains, you can't make the search case-insensitive. I don't know this very well, but the | appears to be a regex character. pandas.Series.str.contains might be using the same syntax as what the Python module re does to search strings.

                Looking up the pandas documentation, pandas.Series.str.contains does in fact use the re module. .lower() works too, but the re module could be more familiar.

You might be confusing .str.contains() from pandas, which exists and is applied to series. In this case you can use in or not in operators. 
Here's a full guide on how to address the issue Does Python have a string 'contains' substring method?
From pandas docs:
  
Series.str.contains(self, pat, case=True, flags=0, na=nan, regex=True).
  Test if pattern or regex is contained within a string of a Series or Index.
Not too sure if you're just checking for certain strings in a string, but i'm pretty sure .contains isn't a python thing, 
try this:
for "string" in f:
    # do whatever
                Also, the for-loop is assigns an object from an iterable to a variable per iteration. You can't assign objects to a string. This is likely intended to be an if-statement.
