Using a for loop

Example:1

s = 'KDnuggets,  is,  a,  fantastic,  resource'
a = s.split(',')
result = []
for item in a:
    result.append(item.strip())

print(result)

Output

['KDnuggets', 'is', 'a', 'fantastic', 'resource']


** Process exited - Return Code: 0 **
Press Enter to exit terminal

Using map() with a lambda function

Example:2

s = 'KDnuggets,  is,  a,  fantastic,  resource'
a = list(map(lambda item: item.strip(), s.split(',')))
print(a)

Output

['KDnuggets', 'is', 'a', 'fantastic', 'resource']


** Process exited - Return Code: 0 **
Press Enter to exit terminal

Using a list comprehension with the strip() method

Example:3

s = 'KDnuggets,  is,  a,  fantastic,  resource'
a = [item.strip() for item in s.split(',')]
print(a)

Output

['KDnuggets',  'is', 'a', 'fantastic', 'resource']
** Process exited - Return Code: 0 **
Press Enter to exit terminal

Conclusion

All three approaches will give the same output, which removes the whitespace around each item in the list. You can choose the approach that you find most readable convenient for your specific use case.
