Python multiple comparison style?

Question

I am wondering if there is a way to do the following in a more compact style:

if (text == "Text1" or text=="Text2" or text=="Text3" or text=="Text4"): do_something() 

The problem is that I have more than 4 comparisons in the if statement, and it starts to look pretty long, ambiguous, and ugly. Any ideas?

Answer 1

How about this:

 if text in ( 'Text1', 'Text2', 'Text3', 'Text4' ): do_something() 

I always found it simple and elegant.

Answer 2

The answer "if text in" is good, but you can also think of a re (regular expression) package if your text strings match the pattern. For example, taking your example literally, “Text” followed by a number will be a simple regular expression.

Here is an example that should work for “Text,” followed by a digit. \ Z matches the end of a line, the digit \ d a.

 if re.match('Text\d\Z', text): do_something()
