But how can you return the element itself, instead of True or False. This task can be performed using naive method and hence can be reduced to list comprehension as well. By specifying re.IGNORECASE as the argument flags of functions such as re.search() and re.fullmatch(), case-insensitive comparison is possible. Numpy copysign Change the sign of x1 to that of x2, element-wise. We can directly use this operator in the following way: We can also convert this into a function, for ease of use.

I recommend you check out the following tutorial with video to shed some light on the background information here: Generally, I like list comprehension more than the filter() function because the former is more concise (e.g., no need to convert the result to a list) and slightly faster. This can be used as a filter for messages. The whole problem of partial string matching consists of finding a function that gives a meaningful similarity score between two strings. In earlier versions, you can use re.search() with ^ and $ to do the same. For example, if my_list = ['f', 'foo'] and test1 = ['f', 'foo'] and test2 = ['foo', 'f'] without sorting, one of the success and the other will be faild.
