How to Make Gradebook using Python Pandas

1. How to Make Gradebook using Python Pandas? As a student, it’s always helpful to have a grade book to track your progress in different subjects. While there are many apps available online for this purpose, creating a guidebook using Python can be a great learning experience. In this blog post, we will explore how to create a grade book using the Pandas library in Python. Explaining Pandas and Their Features Pandas is a Python library that is widely used for data manipulation and analysis. It provides easy-to-use data structures and data analysis tools for handling structured data. The two primary data structures provided by Pandas are Series (1-dimensional) and DataFrame (2-dimensional). Pandas provides various operations for data manipulation like merging, grouping, and filtering of data.

2. Creating a Gradebook using Pandas To create a gradebook, we will be using Pandas’ DataFrame data structure. The DataFrame will contain student names, subject names, and their corresponding grades. We can create a DataFrame by passing a dictionary to the constructor with keys as column names and values as lists. Here is the code for creating a simple gradebook: import pandas as pd # create a dictionary of student names, subjects and grades data = { 'Student Name': ['Alice', 'Bob', 'Charlie'], 'Subject': ['Maths', 'Science', 'English'], 'Grade': [90, 85, 92] }

3. # create a dataframe from the dictionary df = pd.DataFrame(data) # print the dataframe print(df) Output: Student Name Subject Grade 0 Alice Maths 90 1 Bob Science 85 2 Charlie English 92 We can see that the data frame contains three columns: Student Name, Subject, and Grade. Each row corresponds to a student’s grade in a particular subject.

4. We can also perform various operations on the DataFrame to manipulate the data, such as sorting the data by a specific column, filtering the data based on certain conditions, and grouping the data by specific columns. For example, to sort the data by grade in descending order, we can use the following code: # sort the dataframe by grade in descending order sorted_df = df.sort_values('Grade', ascending=False) # print the sorted dataframe print(sorted_df) Output: Student Name Subject Grade 2 Charlie English 92 0 Alice Maths 90

5. 1 Bob Science 85 We can see that the DataFrame is now sorted by Grade in descending order. Conclusion In this blog post, we have seen how to create a grade book using the Pandas library in Python. We have also explored some of the basic operations that we can perform on the DataFrame data structure to manipulate and analyze the data. By using Pandas, we can easily create and analyze a grade book, which can be helpful for students and teachers alike.
