document = 'document.txt'
file = open(document, 'r')
# 'r' to read. it can be replaced with:
# 'w' to write (overwrite)
# 'a' to append (add to the end)
# 'w+' makes a new file if one does not already exist of that name
# 'a+' same as 'w+' but appends if the file does exist
# 'x' creates file for writing, but fails if file already exists
##go to beginning of document. not required but good for consistency.
file.seek(0)
##print all lines in document, except empty lines:
for line in file:
k = line.strip()
print k
##close the file after you are done
file.close()
##this also works to open a file, and is more error proof:
with open(document) as filestream:
for i in filestream:
k = i.strip()
print kread file rust
