1. Find String in List in Python. Use the for Loop to Find Elements From a List That Contain a Specific Substring in Python. 2. Use the filter() Function to Find Elements From a Python List Which Contain a Specific Substring. 3. Use the Regular Expressions to Find Elements From a Python List Which Contain a Specific Substring.

Explain further. You want to find "fox" inside ["the", "quick", "brown", "fox", "jumps"] ? Correct?

Yes

mylist = ["the", "quick", "brown", "fox", "jumps"] if "fox" in mylist: do_something() else: do_nothing()

Is this faster than index try except TypeError?

it presumably is, because list.index has function overhead and this doesn't, you shouldn't use list.index unless you want to know exactly where the string is

Is this faster than index try except TypeError?

Even it's slower, do you know exact index of item for all cases
