Calculate Time Difference Between Two Pandas Columns in Hours and Minutes
To compute the time difference between two Pandas columns in hours and minutes, you can leverage the astype method on the datetime.timedelta returned by the Pandas timestamp difference. Here's a detailed explanation:
import pandas</p><h1 id="Create-a-sample-dataframe-with-todate-and-fromdate-columns">Create a sample dataframe with 'todate' and 'fromdate' columns</h1><p>data = {'todate': [pd.Timestamp('2014-01-24 13:03:12.050000'), pd.Timestamp('2014-01-27 11:57:18.240000'), pd.Timestamp('2014-01-23 10:07:47.660000')],</p><div class="code" style="position:relative; padding:0px; margin:0px;"><pre class="brush:php;toolbar:false"> 'fromdate': [pd.Timestamp('2014-01-26 23:41:21.870000'), pd.Timestamp('2014-01-27 15:38:22.540000'), pd.Timestamp('2014-01-23 18:50:41.420000')]}
df = pd.DataFrame(data)
Calculate the time difference between the two columns
df['diff'] = df['fromdate'] - df['todate']
Convert the difference to hours using the as_type method
df['diff_in_hours'] = df['diff'].astype('timedelta64[h]')
This approach generates the following output, with the time difference expressed in hours:
</p> <div class="code" style="position:relative; padding:0px; margin:0px;"><pre class="brush:php;toolbar:false"> todate fromdate diff diff_in_hours
0 2014-01-24 13:03:12.050 2014-01-26 23:41:21.870 2 days 10:38:09.82 58
1 2014-01-27 11:57:18.240 2014-01-27 15:38:22.540 0 days 03:41:04.30 3
2 2014-01-23 10:07:47.660 2014-01-23 18:50:41.420 0 days 08:42:53.76 8
By utilizing this tailored method, you can efficiently convert the time difference between timestamps into hours and minutes, providing you with a more concise representation of the elapsed time.

Python is suitable for data science, web development and automation tasks, while C is suitable for system programming, game development and embedded systems. Python is known for its simplicity and powerful ecosystem, while C is known for its high performance and underlying control capabilities.

You can learn basic programming concepts and skills of Python within 2 hours. 1. Learn variables and data types, 2. Master control flow (conditional statements and loops), 3. Understand the definition and use of functions, 4. Quickly get started with Python programming through simple examples and code snippets.

Python excels in gaming and GUI development. 1) Game development uses Pygame, providing drawing, audio and other functions, which are suitable for creating 2D games. 2) GUI development can choose Tkinter or PyQt. Tkinter is simple and easy to use, PyQt has rich functions and is suitable for professional development.

You can learn the basics of Python within two hours. 1. Learn variables and data types, 2. Master control structures such as if statements and loops, 3. Understand the definition and use of functions. These will help you start writing simple Python programs.

Python is easier to learn and use, while C is more powerful but complex. 1. Python syntax is concise and suitable for beginners. Dynamic typing and automatic memory management make it easy to use, but may cause runtime errors. 2.C provides low-level control and advanced features, suitable for high-performance applications, but has a high learning threshold and requires manual memory and type safety management.

To maximize the efficiency of learning Python in a limited time, you can use Python's datetime, time, and schedule modules. 1. The datetime module is used to record and plan learning time. 2. The time module helps to set study and rest time. 3. The schedule module automatically arranges weekly learning tasks.

Python is widely used in the fields of web development, data science, machine learning, automation and scripting. 1) In web development, Django and Flask frameworks simplify the development process. 2) In the fields of data science and machine learning, NumPy, Pandas, Scikit-learn and TensorFlow libraries provide strong support. 3) In terms of automation and scripting, Python is suitable for tasks such as automated testing and system management.

Python excels in automation, scripting, and task management. 1) Automation: File backup is realized through standard libraries such as os and shutil. 2) Script writing: Use the psutil library to monitor system resources. 3) Task management: Use the schedule library to schedule tasks. Python's ease of use and rich library support makes it the preferred tool in these areas.
