Python CSV export writing characters to new lines - list

Question

I have been using multiple code snippets to create a solution that will allow me to write a list of players in a football team to a csv file.
import csv
data = []
string = input("Team Name: ")
fName = string.replace(' ', '') + ".csv"
print("When you have entered all the players, press enter.")
# while loop that will continue allowing entering of players
done = False
while not done:
a = input("Name of player: ")
if a == "":
done = True
else:
string += a + ','
string += input("Age: ") + ','
string += input("Position: ")
print (string)
file = open(fName, 'w')
output = csv.writer(file)
for row in string:
tempRow = row
output.writerow(tempRow)
file.close()
print("Team written to file.")
I would like the exported csv file to look like this:
player1,25,striker
player2,27,midfielder
and so on. However, when I check the exported csv file it looks more like this:
p
l
a
y
e
r
,
2
5
and so on.
Does anyone have an idea of where i'm going wrong?
Many thanks

Your string is a single string. It is not a list of strings. You are expecting it to be a list of strings when you are doing this:
for row in string:
When you iterate over a string, you are iterating over its characters. Which is why you are seeing a character per line.
Declare a list of strings. And append every string to it like this:
done = False
strings_list = []
while not done:
string = ""
a = input("Name of player: ")
if a == "":
done = True
else:
string += a + ','
string += input("Age: ") + ','
string += input("Position: ") + '\n'
strings_list.append(string)
Now iterate over this strings_list and print to the output file. Since you are putting the delimiter (comma) yourself in the string, you do not need a csv writer.
a_file = open(fName, 'w')
for row in strings_list:
print(row)
a_file.write(row)
a_file.close()
Note:
string is a name of a standard module in Python. It is wise not to use this as a name of any variable in your program. Same goes for your variable file
