Regex Output Count - python-3.x

Question

I am trying to count the output of a regex search I am conducting on a dataset but for some reason my count is off by a lot. I was wondering what I am doing wrong and how I can get an official count. I should have around 1500 matches but I keep getting an error that says "'int' object is not iterable".
import re
with open ('Question 1 Logfile.txt' , 'r') as h:
results = []
count = []
for line in h.readlines():
m = re.search(r'(((May|Apr)(\s*)\w+\s\w{2}:\w{2}:\w{2}))', line)
t = re.search(r'(((invalid)(\s(user)\s\w+)))',line)
i = re.search(r'(((from)(\s\w+.\w+.\w+.\w+)))', line)
if m and t and i:
count += 1
print(m.group(1),' - ',i.group(4),' , ',t.group(4))
print(count)

You want to increment the number of times you satisfy a condition over a series of loop iterations. The confusion here seems to be how exactly to do that, and what variable to increment.
Here's a small example that captures the difficulty you've encountered, as described in OP and in OP comments. It's meant as a learning example, but it does also provide a couple of options for a solution.
count = []
count_int = 0
for _ in range(2):
try:
count += 1
except TypeError as e:
print("Here's the problem with trying to increment a list with an integer")
print(str(e))
print("We can, however, increment a list with additional lists:")
count += [1]
print("Count list: {}\n".format(count))
print("Most common solution: increment int count by 1 per loop iteration:")
count_int +=1
print("count_int: {}\n\n".format(count_int))
print("It's also possible to check the length of a list you incremented by one element per loop iteration:")
print(len(count))
Output:
"""

Hope that helps. Good luck learning Python!
