Working with files and dictionaries - OmarSinno - Oct-30-2017

So,

txt = open('testfile.txt','r')

d= {}

numLines = 0
#reading = txt.readlines()
read = txt.readline()
print(read)

for line in txt.readlines():
    numLines += 1
    #print(numLines)
    if numLines not in d:
        d[numLines] = [txt.readline()]
print(d)

It's giving me the following:

Output:
{1: [''], 2: [''], 3: ['']}

I actually want it to count the number of lines, and for example, in line number 1, I want the values of the dictionary to have the contents of the file split into a list.

from collections import defaultdict

d = defaultdict(list)

for numLines, line in enumerate(txt.readlines(), 1):
    d['file_content'].append(line)

print(num_lines) # gives you the number of the lines

# or you can loop over the lines without enumerate and...
print(len(d[file_content'])) # gives you the length of the value of type list in 'd' which is the same as the above print
