Data are overwrite how to solve that-CodePudding

Data are overwritten in pandas how to resolve these problem...... How I get out of for loop to solve these problem kindly recommend any solution for that However, with every iteration through the loop, the previously extracted data is overwritten. How can I solve this problem?

I think you need to define item=dict() inside the for loop. Otherwise this is the same, single item object used in all the loop iterations.
Try this:
