Pandas: Convert DataFrame column type from string to datetime
Pandas: DataFrame Exercise-41 with Solution
Write a Pandas program to convert DataFrame column type from string to datetime.
Sample data:
String Date:
0 3/11/2000
1 3/12/2000
2 3/13/2000
dtype: object
Original DataFrame (string to datetime):
0
0 2000-03-11
1 2000-03-12
2 2000-03-13
Sample Solution :
Python Code :
import pandas as pd
import numpy as np
s = pd.Series(['3/11/2000', '3/12/2000', '3/13/2000'])
print("String Date:")
print(s)
r = pd.to_datetime(pd.Series(s))
df = pd.DataFrame(r)
print("Original DataFrame (string to datetime):")
print(df)
Sample Output:
String Date: 0 3/11/2000 1 3/12/2000 2 3/13/2000 dtype: object Original DataFrame (string to datetime): 0 0 2000-03-11 1 2000-03-12 2 2000-03-13
Explanation:
The above code first creates a Pandas Series object s containing three strings that represent dates in 'month/day/year' format.
r = pd.to_datetime(pd.Series(s)): This line uses the pd.to_datetime() method to convert each string date into a Pandas datetime object, and then create a new Pandas Series object ‘r’ containing these datetime objects.
df = pd.DataFrame(r): Finally, the code creates a new Pandas DataFrame ‘df’ from ‘r’ by passing it as the only column of the DataFrame. The resulting DataFrame df contains a single column of datetime objects representing the dates from the original Series ‘s’
