![]() Please, note the order in this type of indexing: first you specify column label and then row. We can select necessary rows and columns using it’s labels: df Out: 4 To extract data from pandas DataFrame we can use direct indexing or accessors. import pandas as pd import numpy as np cols = rows = data = np.random.randint(0, 100, size=(5, 5)) df = pd.DataFrame(data, columns=cols, index=rows) df.head() Out: We will use this data as an example during the explanations in the article. Let’s get started.įor this article I’ve created a sample DataFrame with random numbers to play with it. And in today’s article I will list those techniques with code samples and some explanations. The pandas library has many techniques that make this process efficient and intuitive. It is important to be able to extract, filter, and transform data from DataFrames in order to drill into the data that really matters. You can use the format codes and create your own format for the date and time string.In order to get insights from data you have to play with it a little. The presented examples explain the usage of format codes, but are not limited to. Python Program from datetime import datetimeĬoncluding this Python Tutorial, we learned how to format datetime object as per our requirement. We will use %M for the two digit representation of minutes from datetime object and %S for the two digit representation of seconds from datetime object. In this example, we will learn how to format time as MM:SS using datetime object. Output Formatted Time: 22:44:59 Python DateTime – Format Time – MM:SS Print("Formatted Date:", time1) Try Online Python Program from datetime import datetime We will use %H for the two digit representation of hours from datetime object, %M for the two digit representation of minutes from datetime object and %S for the two digit representation of seconds from datetime object. In this example, we will learn how to format time as HH:MM:SS using datetime object. Output Formatted Date: 18-06-2020 Python DateTime Format – HH:MM:SS dd meaning day represented with two digit string, mm is month represented with two digit string and YYYY is year represented with four digit string. In the following program, we will learn how to format date as dd-mm-YYYY. Output Formatted Date: 06-18-2020 Python DateTime Format – dd-mm-YYYY ![]() mm is month represented with two digit string, dd meaning day represented with two digit string and YYYY is year represented with four digit string. In the following program, we will learn how to format date as mm-dd-YYYY. Output Formatted Date: Python DateTime Format – mm-dd-YYYY In the following program, we will learn how to format date as dd/mm/YYYY. Output Formatted Date: Python DateTime Format – dd/mm/YYYY Print("Formatted Date:", date1) Try Online In the following program, we will learn how to format date as mm/dd/YYYY. Output Formatted DateTime: 22:47:12 Python DateTime Format – mm/dd/YYYY Print("Formatted DateTime:", time1) Try Online What strfime() function does is that, it replaces %d with the two digit string for the day of datetime.datetime object, replaces %m with two digit representation of month, replaces %Y with the four digit representation of the year of this datetime.datetime object, and so on, as per the format codes. The format string would be “%d/%m/%Y %H:%M:%S”. dd meaning day represented with two digit string, mm is month represented with two digit string, YYYY is year represented with four digit string, HH is hours represented with two digit string, MM is for minutes and SS is for seconds. In the following program, we will learn how to format date as dd/mm/YYYY HH:MM:SS. Python DateTime – Format Date & Time – dd/mm/YYYY HH:MM:SS We will learn much about these in the following example programs. These format codes if specified in the format, will be replaced with their corresponding values present in datetime.datetime object. Format Codesįollowing is the list of format codes that we use while formatting a string from datetime object using strftime() function. Strftime() function returns formatted datetime as string based on the given format. strftime(format)įormat is string that describes the specified format to strftime() function for creating date and time string from datetime.datetime object. Following is the syntax of strftime() function.
