Pandas: Add leading zeros to the integer column in a pandas series and makes the length of the field to 8 digit

Pandas: String and Regular Expression Exercise-3 with Solution

Write a Pandas program to add leading zeros to the integer column in a pandas series and makes the length of the field to 8 digit.

Sample Solution:

Python Code :

import pandas as pd
nums = {'amount': [10, 250, 3000, 40000, 500000]}
print("Original dataframe:")
df = pd.DataFrame(nums)
print(df)
print("\nAdd leading zeros:")
df['amount'] = df['amount'].apply(lambda x: '{0:0>8}'.format(x))
print(df)

Sample Output:

Original dataframe:
   amount
0      10
1     250
2    3000
3   40000
4  500000

Add leading zeros:
     amount
0  00000010
1  00000250
2  00003000
3  00040000
4  00500000
