Check if csv has header in python

Consider the following csv data

id, name, editor
1, Bhupesh, NeoVim
2, Mark, VSCode
3, Jennifer, JetBrains

1, Banana, 34
2, Apples, 5
3, Orange, 33
4, Mango, 12

The csv.Sniffer class provides a method called has_header which return True if the first row appears to be a header

import csv

csv_with_header = """
id, name, editor
1, Bhupesh, NeoVim
2, Mark, VSCode
3, Jennifer, JetBrains
"""

csv_without_header = """
1, Banana, 34
2, Apples, 5
3, Orange, 33
4, Mango, 12
"""

def has_header(file): 
        with open(file, 'r') as csvfile: 
        sniffer = csv.Sniffer()
        return sniffer.has_header(csvfile.read())


print(has_header('csv_with_header.csv'))
# true
print(has_header('csv_without_header.csv'))
# false
