How can I round each entry (which is a tuple) of a pandas dataframe in Python?

Question

I am trying to get my cell values (ticker symbols) from the excel sheet, but cannot figure out how to specify rows/columns to use. The ws.iter_rows() method is not accepting the string. 

Here is the code I am using:

wb = openpyxl.load_workbook('/Users/SPAC_price_data.xlsx')

ws = wb['Common share price history']

for row in ws.iter_rows('A1:A36'):

    for cell in row:

            print(str(cell.value))

The error is:

    ---------------------------------------------------------------------------

Answer 1

The input parameters for the iter_rows() must be an integer. 

Replace:

for row in ws.iter_rows('C{}:C{}'.format(ws.min_row,ws.max_row)):

With:

for row in ws.iter_rows(ws.min_row,ws.max_row):
