I have a text document in the format of:
-1+1
-1-1
+1+1
-1-1
+1-1
...
I want to have a program that counts how many lines have -1+1 lines and +1-1 lines. The program would then just need to return the value of how many lines are like this.
I have written the code:
f1 = open("results.txt", "r")
fileOne = f1.readlines()
f1.close()
x = 0
for i in fileOne:
if i == '-1+1':
x += 1
elif i == '+1-1':
x += 1
else:
continue
print x
But for some reason, it always returns 0 and I have no idea why.
Use collections.Counter
instead:
import collections
with open('results.txt') as infile:
counts = collections.Counter(l.strip() for l in infile)
for line, count in counts.most_common():
print line, count
Most of all, remove whitespace (the newline specifically, but any other spaces or tabs might interfere too) when counting your lines.
