Reading data from excel using openpyxl

readExcel.py

#
# I hate the documentation of openpyxl and it took me a while to undertand their stuff. So I decided to write down this code.
# Has some wrapper functions that reads all rows from the excel sheet and also a function to read a particular row.
# Add some code to the functions if you wish to do something on fly like adding values to list and sorting them later.

from openpyxl import load_workbook

# Reads all rows
def read_all_rows(workSheet):
	# You need to set an offset if the first row is your column headings
	for row in workSheet.iter_rows(row_offset=1):
		print "\n"
		for cell in row:
			print cell.value

# Prints the data in a particular column
def read_column(workSheet, columnNumber):
	# You need to set an offset if the first row is your column headings
	for row in workSheet.iter_rows(row_offset=1):
		print row[columnNumber].value


# ------------------------------ MAIN ---------------------------------------

workBook = load_workbook(filename='errortype.xlsx', read_only=True, use_iterators=True)
workSheet = workBook['Sheet1']
#read_all_rows(workSheet)
read_column(workSheet, 0)

@armaandhir by setting the rowoffset to 1, it prints an extra row containing null values..do you know why?
