- How to convert strings numbers to integers in a list? 4 answers
I realize my wording for the title isn't the best, but I hope an example will clear this up.
How would I convert a list like
example_list = ["asdf" , "4", "asdfasdf" , "8" , "9" ,"asdf"]
to a list like
converted_list = ["asdf" , 4, "asdfasdf", 8 , 9 , "asdf"]
So basically how do I make a list where strings that can be converted to integers are converted to integers while strings that cannot be converted remain as strings?
As a side note, how would I afterwards test in a for loop if each item in the converted_list is an integer or not?
The context for this issue is that I am trying to convert headers in pandas to integers if possible, since all the integers are strings as of now. And then if the column had a stringed number as a header, I would take the mean of the column. Right now, I have made all the headers into a list.
You can use a list comprehension with a ternary to determine whether or not each element of the list is a number.
>>> [int(n) if n.isdigit() else n for n in example_list]
['asdf', 4, 'asdfasdf', 8, 9, 'asdf']
