How to convert list to comma-separated string in Python

Python has a built-in String join() method by using that we can convert a list to an comma-separated.

Here is an example that combines the following list into a comma-separated string.

myList = ("a", "b", "c")

x = ",".join(myList)

print(x)

Output:

a,b,c

If you want convert a non-string types (like numbers, floats, booleans) then you can do it like this.

myList = (1, 5, 7)

x = ",".join(map(str, myList))

print(x)

In the above code, we first converted the list of numbers into a string by executing the str() function on each value in the array then combined it into a comma-separated string using join() method.
