```How do I know write the loop code for the table for both inputfiles, Table1.txt and Table2.txt and make a third table from the elements multiplied in table1.txt and table2.txt. I'm trying to Check the size of the two tables to make sure they both have the same number of rows and columns o If the tables are not the same size print an error message  Once you have read the data from each file create a third table  The elements in the third table are the result of multiplying each element in the first table by the corresponding element in the second table:
thirdTable [i] [j] = firstTable[i] [j] * secondTable[i] [j

Here is my code so far:

def main():
print("Table One")
(row1, column1, table1) = readInput("Table 1.txt")
print("Table Two")
(row2, column2, table2) = readInput("Table 2.txt")
return()

table = []
inputFile = open(filename, "r")

#  Read the first line containing the number of rows and columns

#  split the line into two strings
(row, column) = line.split()

#  convert the strings into integers
row = int(row)
column = int(column)

#  loop on the file container, reading each line

for line in inputFile :
line = line.rstrip()  #strip off the newline
dataList = line.split()  #  split the string into a list
table.append(dataList)

#  Loop through the table and convert each element to an integer

for i in range(row):
for j in range (column):
table[i] [j] = int(table[i] [j])  # convert the string to an integer
print(" %3d" % (table[i] [j]), end = " ")
print()

inputFile.close()  #  close the file
return(row, column, table)

#  return the number of rows and columns

main()
