Question

properties = ["color", "font-size", "font-family", "width", "height"]


inPath = "style.css"
outPath = "output.txt"

#Open a file for reading
file = open(inPath, 'rU')
if file:
    # read from the file
    filecontents = file.read()
    file.close()
else:
    print "Error Opening File."

#Open a file for writing
file = open(outPath, 'wb')
if file:
    for i in properties:
        search = i
        index = filecontents.find(search)   
        file.write(str(index), "\n")
    file.close()
else:
    print "Error Opening File."

seems to work, but:

• It only searches a keyword once?
• Its not writing to the output file. function takes exactly 1 argument
• I don’t want it to print the index actually, but the number of time the keyword appears.

Many thanks

Answer 1

First, you want .count(search), not .find(search), if what you’re looking for is # of occurrences.

Second, .write() only takes a single parameter – if you want to write a newline, you need to concatenate it first, or call .write() twice.

Third, doing for i in properties: search = i is redundant; just use the name you want in your for loop.

for search in properties:
    cnt = filecontents.count(search)
    file.write(str(cnt) + "\n")
