how to define a function that gets the number of columns in a pandas dataframe that takes the dataframe as the function's parameter

Question

say I got multiple pandas dataframes and I want to check their number of columns and create a def function that does that, how? Already tried on my own but when I the following code it returns a type error

import pandas as pd def load_csv(filename): filename = pd.read_csv(filename) return filename def columns_count(f): f = load_csv(f) columns = f.shape[1] return columns

Answer 1

Code to loop through dataframes and count number of columns

def count_num_cols(df): return len(df.columns) # or df.shape[1] list_of_paths = ["C://Users//file.txt", ] for a_path in list_of_paths: df = pd.read_csv(a_path) print(count_num_cols(df.shape[1])
