16. Get Length of Integer in Column

Write a Pandas program to get the length of the integer 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 sale_amount:")
df['sale_amount_length'] = df['sale_amount'].map(str).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 sale_amount:
  company_code date_of_sale  sale_amount  sale_amount_length
0         Abcd   12/05/2002      12348.5                   7
1         EFGF   16/02/1999     233331.2                   8
2      skfsalf   25/09/1998         22.5                   4
3      sdfslew   12/02/2022    2566552.0                   9
4       safsdf   15/09/1997         23.0                   4
