Strip white spaces from CSV file

Question

I need to stripe the white spaces from a CSV file that I read

import csv

aList=[]
with open(self.filename, \'r\') as f:
    reader = csv.reader(f, delimite         


        

Answer 1

Read a CSV (or Excel file) using Pandas and trim it using this custom function.

#Definition for strippping whitespace
def trim(dataset):
    trim = lambda x: x.strip() if type(x) is str else x
    return dataset.applymap(trim)

You can now apply trim(CSV/Excel) to your code like so (as part of a loop, etc.)

dataset = trim(pd.read_csv(dataset))
dataset = trim(pd.read_excel(dataset))
