How to add iteration values in dictionary?

Question

I want to make the dictionary, (key: days, value: occurence) in a textfile
First, I have to extract lines which starts with 'From' and after split the line, In the line, extract the second word which is 'days' like monday, tuesday... And finally. Add the days as the key and occurences as the value in dictionary
The expected result is..
{'Fri':20, 'Thu':6, 'Sat':1}

I wrote as follow:

file=open('mbox-short.txt')
counts=dict()
for line in file:
line=line.rstrip()
If line.startswith('From:'):continue
If line.starswith('From'):
words=line.split()
days=words[2]
for day in days:
counts[day]=counts.get(day,0)+1
else: continue
Print counts

Is there anyone who can solve this problem?
Help me out please-

Answer 1

Okay so here is the corrected code. Hopefully complies with Py2. Haven't used that in over a year.
The readlines method is required as I mentioned earlier.
Your code for counting the occurances was iterating the characters in the day string instead.
My changes should be easy to understand. I hope.

file=open('mbox-short.txt')
counts=dict()
lines = file.readlines()
for line in lines:
if line.startswith('From:'):continue
if line.startswith('From'):
words=line.split()
day=words[2]
if day in counts:
counts[day] = counts[day]+1
else:
counts[day] = 1
print counts

The IDLE editor tends to indent for me. 4 spaces for each indent. When I leave a construct I just backspace 4 times.
There is an indent and dedent shortcut in IDLE which I sometimes use to indent and remove indentation in code blocks.
Notepad++ has this shortcut too, though I don't know if it indents using tabs or 4 spaces. Select the code you want to indent and click tab. To dedent click shift tab.

First, open needs an access mode. In your case the program needs to read the file. Add the access argument next to the file path. "r" for read.
file = open(file, accessmode)
Then use readlines to retrieve the lines in the file.
lines = file.readlines()
Then you can begin to iterate thru them.
For the next part? The occurances, is it how many times a day appears in the file?
Also can I see an example of a line in the file.

Answer 4

Reading the file is no problem cuz default value is read mode.
Accurrnce , means how many times the days are in the file :)
File is like..

You did really good job thanks!
I got a result what I want
But I have a question. Whenever I write programing on notepad++ connected with command prompt
In notepad, it shows me where is indented lines occur with (-) sign.
How to adjust indented line easily? Even I always check the column number on the bottom of the notepad , sometimes they make different indented lines.. I dont know how to figure out..
Can you let me know some tips for adjusting indented lines?

Ok. Thank you for sharing your tip-
I will imply it in that way :)
