Pandas: Get the length of the string present of a given column in a DataFrame

Pandas: String and Regular Expression Exercise-15 with Solution

Write a Pandas program to get the length of the string present of a given column in a DataFrame.

Sample Solution:

Python Code :

import pandas as pd
df = pd.DataFrame({
    'company_code': ['Abcd','EFGF', 'skfsalf', 'sdfslew', 'safsdf'],
    '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("\nLength of the string in a column:")
df['company_code_length'] = df['company_code'].apply(len)
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      skfsalf    25/09/1998         22.5
3      sdfslew    12/02/2022    2566552.0
4       safsdf    15/09/1997         23.0

Length of the string in a column:
  company_code         ...         company_code_length
0         Abcd         ...                           4
1         EFGF         ...                           4
2      skfsalf         ...                           7
3      sdfslew         ...                           7
4       safsdf         ...                           6
