Python not reading file, returning empty result

Question

aaa.txt:

aszczx
d
as
w
ad

python script:

f = open('aaa.txt','r')
f.read()
f.close()

Console:

C:\Python27>test.py

C:\Python27>

Why is it not displaying the contents of the file?

Thanks,

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

For instance you could do something like this:

with open('aaa.txt') as infp:
    data = infp.read()

print data # display data read

Using with will also close the file for your automatically

Note that the asker used read() while you used readlines() - the two are different. readlines() will return a list of strings, while read() will return a big string.

You can save the lines you read in to a variable, then print it later.

lines = f.read()
# Later...
print lines
