finding keywords frequency in a c code using python excluding comments

I want to create a program, that can count the frequency of keywords used in a C code, excluding the commented ones or inside printf command.

C

printf

def counting(f, word):
counter = 0
for w in f.split():
if word==w:
counter += 1
return counter

key=open('c_keywords.txt')
keyw=key.read().split()
file=open('a1.cpp').read()

for key in keyw:
x = counting(file,key)
if x != 0:
print (key, ":", x)

Here is an example of how to do it with a textfile, you can edit the text.txt and use your C code file instead

with open('text.txt', 'r') as doc:
print('opened txt')
for words in doc:
wordlist = words.split()

for numbers in range(len(wordlist)):
for inner_numbers in range(len(wordlist)):
if inner_numbers != numbers:
if wordlist[numbers] == wordlist[inner_numbers]:
print('word: %s == %s' %(wordlist[numbers], wordlist[inner_numbers]))


Use:

f = open('keywords_c.txt')

count = 0
words =

for x in f:
w = x.split()
for a in w:
words.append(a)
print(words)

cpp = open('Simple_c.cpp')

program =

for y in cpp:

if y.startswith('printf'):
continue
elif y.startswith('//'):
continue
else:
w = y.split()
for b in w:
if any(b in s for s in words):
count +=1


print(count)
