My Code:
import pandas as pd
laptops = pd.read_csv('laptops.csv', encoding='Latin-1')
def tidy_columns(col):
col = col.strip()
col = col.replace('Operating System', 'os')
col - col.replace(' ','_')
col = col.replace('(','')
col = col.replace(')','')
col = col.lower()
return col
new_columns = []
for column in laptops.columns:
new_columns.append(tidy_columns(column))
laptops.columns = new_columns
What I expected to happen:
