I made this function that calculates the mode of a list. I was just wandering if there were any other ways of finding the mode that are more simpler than what I have done. Also there could be a possibility that my code does’nt work.

```
def mode(list_in):
count_dict = {}
for x in list_in: #makes a dictionary of the numbers in the list and how frequently they appear.
if x not in count_dict:
count_dict[x] = 1
else:
count_dict[x] += 1
count_list = []
for x in count_dict: #makes a list of the frequencies
count_list.append(count_dict[x])
maximum = max(count_list)#finds maximum frequency
mode = []
for x in count_dict: #adds the numbers corresponding to the maximum frequency to a list
if count_dict[x] == maximum:
mode.append(str(x))
return ",".join(mode)
```
