Pandas: Check whether only space is present in a given column of a DataFrame

Pandas: String and Regular Expression Exercise-14 with Solution

Write a Pandas program to check whether only space is present in a given column of a DataFrame.

Sample Solution:

Python Code :

import pandas as pd
df = pd.DataFrame({
    'company_code': ['Abcd','EFGF ', '  ', 'abcd', ' '],
    'date_of_sale ': ['12/05/2002','16/02/1999','25/09/1998','12/02/2022','15/09/1997'],
    'sale_amount': [12348.5, 233331.2, 22.5, 2566552.0, 23.0]})

print("Original DataFrame:")
print(df)
print("\nIs space is present?")
df['company_code_is_title'] = list(map(lambda x: x.isspace(), df['company_code']))
print(df)

Sample Output:

Original DataFrame:
  company_code date_of_sale   sale_amount
0         Abcd    12/05/2002      12348.5
1        EFGF     16/02/1999     233331.2
2                 25/09/1998         22.5
3         abcd    12/02/2022    2566552.0
4                 15/09/1997         23.0

Is space is present?
  company_code          ...          company_code_is_title
0         Abcd          ...                          False
1        EFGF           ...                          False
2                       ...                           True
3         abcd          ...                          False
4                       ...                           True

Python: Tips of the Day

Returns True if there are duplicate values in a flat list, False otherwise

Example:

def tips_duplicates(lst):
  return len(lst) != len(set(lst))

x = [2, 4, 6, 8, 4, 2]
y = [1, 3, 5, 7, 9]
print(tips_duplicates(x))
print(tips_duplicates(y))

Output:

True
False
