Python finds more tables for data comparison

Three tables of data (tens of thousands) need to be compared to see if there are any duplicates. Using excel itself for data verification is obviously a huge amount of data, so consider using python scripts to achieve it.

c_wb = wb3['employee']

a_wb_max_row = len(a_wb['B'])
b_wb_max_row = len(b_wb['B'])
c_wb_max_row = len(c_wb['B'])
