using itertools.chain :
from itertools import chain
print[list[chain.from_iterable[ele.split[","] for ele in l]]]
['60', '78', '70', '77', '80', '74', '90', '75', '100', '74', '110', '75']
The more items you have to flatten chain does it a bit more efficiently:
In [1]: l= ["1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20" for _ in range[100000]]
In [2]: from itertools import chain
In [3]: l= ["1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30" for _ in range[10000]]
In [4]: timeit [list[chain.from_iterable[ele.split[","] for ele in l]]]
100 loops, best of 3: 17.7 ms per loop
In [5]: timeit [item for items in l for item in items.split[","]]
10 loops, best of 3: 20.9 ms per loop

Example
Split a string into a list where each word is a list item:
txt = "welcome to the jungle"
x = txt.split[]
print[x]

Definition and Usage
The split[] method splits
a string into a list.
You can specify the separator, default separator is any whitespace.
Note: When maxsplit is specified, the list will contain the specified number of elements plus one.
Syntax
string.split[separator, maxsplit]
Parameter Values
| separator | Optional. Specifies the separator to use when splitting the string. By default any whitespace is a separator |
| maxsplit | Optional. Specifies how many splits to do. Default value is -1, which is "all occurrences" |
More Examples
Example
Split the string, using comma, followed by a space, as a separator:
txt = "hello, my name is Peter, I am 26 years old"
x = txt.split[", "]
print[x]
Try it Yourself »
Example
Use a hash character as a separator:
txt = "apple#banana#cherry#orange"
x = txt.split["#"]
print[x]
Try it Yourself »
Example
Split the string into a list with max 2 items:
txt = "apple#banana#cherry#orange"
# setting the maxsplit parameter to 1, will return a list with 2 elements!
x = txt.split["#", 1]
print[x]

In this tutorial, we will look at how to split a string into a list of strings on the occurrences of a comma in Python with the help of examples.
How to split a string in Python?
You can use the Python string split[] function to split a string [by a delimiter] into a list of
strings. To split a string by comma in Python, pass the comma character "," as a delimiter to the split[] function.
The following is the syntax –
# split string s by comma s.split[","]
It returns a list of strings resulting from splitting the original string on the occurrences of ",".
Let’s look at some examples.
Split string by comma
Here, we pass comma "," as the delimiter to the string split[] function.
# string with commas s = "Yes, they backed Steve, Emma, and Rohan in the meeting." # split string by comma ls = s.split[","] print[ls]
Output:
['Yes', ' they backed Steve', ' Emma', ' and Rohan in the meeting.']
The resulting list contains words resulting from the split of the original string on occurrences of a comma.
Fix the number of splits
You can also specify the maximum number of splits to be made using the maxsplit parameter. By default, the string split[] function makes all the possible splits.
Let’s only split the above string into two parts at the occurrence of a comma, ","starting from the left. To split the string into two parts, the maxsplit should be 1, because we’re making only one split
resulting in two strings.
# string with commas s = "Yes, they backed Steve, Emma, and Rohan in the meeting." # split string by comma ls = s.split[",", maxsplit=1] print[ls]
Output:
['Yes', ' they backed Steve, Emma, and Rohan in the meeting.']
You can see that the resulting list has only two strings.
Let’s look at another example.
Let’s split the original string into three parts, here we pass maxsplit=2.
# string with commas s = "Yes, they backed Steve, Emma, and Rohan in the meeting." # split string by comma ls = s.split[",", maxsplit=2] print[ls]
Output:
['Yes', ' they backed Steve', ' Emma, and Rohan in the meeting.']
The resulting list has only three strings.
