Python, cannot open a text file

I have a text file named android.txt (with a couple of thousand of lines) which I try to open with python, my code is:

f = open('/home/user/android.txt', 'r')

But when I'm doing:

f.read()

the result is:

''

I chmod 777 /home/user/android.txt but the result remains the same

try making a variable that contains f:read() and printing it

f = open('/home/user/android.txt', 'r')
rf = f:read()
print(rf)

else try making print(repr(f:read()))

The result would be empty string not empty list and it's because your file size is larger than your memory(based on your python version and your machine)! So python doesn't assigned the file content to a variable!

For getting rid of this problem you need to process your file line by line.

with open('/home/user/android.txt') as f :
    for line in f:
         #do stuff with line

You are not displaying the contents of the file, just reading it.

For instance you could do something like this:

with open('/home/user/android.txt') as infp:
    data = infp.read()

print data # display data read

Using with will also close the file for your automatically
