I have multiple string variables that store some text data. I want to perform the same set of tasks on all strings. How can I achieve this in Python?
string_1 = "this is string 1" string_2 = "this is string 2" string_3 = "this is string 3" for words in string_1: return the second word Above is just an example. I want to extract the second word in every string. Can I do something like:
for words in [string_1, string_2, string_3]: return the second word in each string You can use a list comprehension to chain up the second word in those strings. split() breaks your sentence down into word components by consuming spaces.
lines = [string1, string2, string3] >>>lines[0].split() ['this', 'is', 'string', '1'] >>>[line.split()[1] if len(line.split()) > 1 else None for line in lines] ['is', 'is', 'is'] Edit Added conditional checks to prevent indexing failures
line.split() so if there are multiple spaces it still works. Also, the issue with listcomp is that if the sentence has only 1 word, it crashes when accessing the second element.
split without the character argument per your suggestion and added a conditional statement to prevent indexing errors. Thanks for pointing out!Yes you could do
for sentence in [string_1, string_2, string_3]: print(sentence.split(' ')[1]) # Get second word and do something with it This will work assuming that you have minimum of two words in the string and each separated by a space.
