read/print from file - mcmxl22 - Dec-29-2016
I am trying to print a file based on this tutorial, (basic)files, and some other suggestions I found online.
I get nothing in return!
with open('12days.txt', 'r') as fin:
file = fin.readline()
print (file)

As you know readline() reads from the file until 'new line' character is reached.
In [7]: print('\n')
In [8]: print(r'\n')
\n
In [9]:In order to print all file you have to put readline() into a loop.with open('12days.txt', 'r') as fin:
for file in fin.readline():
print(file)

It still returns nothing.

What is the length of the 12days.txt file?
RE: read/print from file - mcmxl22 - Dec-29-2016
The length is 2,232 characters.

try:
with open('12days.txt', 'r') as fin:
for line in fin.readlines():
print(line)Note readlines, not readline
