I am trying to pop a list but it is returning a Type Error?-CodePudding

I am trying to create a list of words with 5 characters. I am using this approach

word = pd.read_csv('words.csv').values.tolist()
for x in word:
    if len(x) != 5:
        word.pop(x)word = pd.read_csv('words.csv').values.tolist()
for x in word:
    if len(x) != 5:
        word.pop(x)

But this set of codes returns this particular error

word.pop(x)
TypeError: 'list' object cannot be interpreted as an integer

Can someone help me understand the Type Error and Troubleshoot it

CodePudding user response：

pop is a function to remove the ith element from a list. I guess from your code that x is not an integer. You can check this with type(x). I think you want the remove function, which

Remove the first item from the list whose value is equal to x. It raises a ValueError if there is no such item.

CodePudding user response：

There is a faster method to do this, depending on what your CSV looks like.

A CSV that looks like this:

WORD
test
david
hello

If you have a csv that looks like the above, you can filter out the non-5 letter words like so:

word = pd.read_csv('words.csv')

word = word[word["WORD"].apply(lambda x : len(x) == 5)]

will output:

david
hello
