Then we create a DataFrame using that NumPy array. This is of course another way of creating DataFrame in Python. Then we print that DataFrame. Now we will use thepd.DataFrame(data, columns = new_columns)where we will pass the new column names as thecolumnsvalue. This will replace the o...

Move the column Biology to Column F to get your desired order as in the sheet “Dataset.” Here, you will get the rearranged column matches to another sheet. It should be noted that while you are using this method, there can not be any merged columns in the table. If there are any ...
We are given two Pandas data frames and these two Pandas dataframes have the same name columns but we need to merge the two data frames using the keys of the first data frame and we need to tell the Pandas to place the values of another column of the second data frame in the f...
TheTreeviewwidget has three columns: Name, Email, and Phone. The first column (#0) is hidden to make the table visually clean.tree.pack(expand=True, fill=tk.BOTH)ensures the table resizes dynamically. Check outHow to Create Labels in Python with Tkinter?
