Pandas: Add leading zeros to the character column in a pandas series and makes the length of the field to 8 digit
Pandas: String and Regular Expression Exercise-4 with Solution
Write a Pandas program to add leading zeros to the character 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'] = list(map(lambda x: x.zfill(10), df['amount']))
print(df)
Sample Output:
Original dataframe: amount 0 10 1 250 2 3000 3 40000 4 500000 Add leading zeros: amount 0 0000000010 1 0000000250 2 0000003000 3 0000040000 4 0000500000
