from xlwt import Workbook, Worksheet, easyxf 
# ... 
# Protect worksheet - all cells will be read-only by default 
my_worksheet.protect = True # defaults to False 
my_worksheet.password = "something_difficult_to_guess" 

# Create cell styles for both read-only and editable cells 
editable = easyxf("protection: cell_locked false;") 
read_only = easyxf("") # "cell_locked true" is default 
# Apply your new styles when writing cells 
my_worksheet.write(0, 0, "Can't touch this!", read_only) 
my_worksheet.write(2, 2, "Erase me :)", editable)
