how to move a column to the beginning in dataframe

col = df.pop("Mid")
df.insert(0, col.name, col)

Here is what the above code is Doing:
1. We’re using the pop() method to remove the column named “Mid” from the df dataframe.
2. We’re using the insert() method to insert the column back into the df dataframe at the 0th index.
3. We’re using the name attribute of the col variable to specify the name of the column.
