Print list without brackets in a single row

Question

I have a list in Python e.g.

names = [\"Sam\", \"Peter\", \"James\", \"Julian\", \"Ann\"]

I want to print the array in a single line withou

Answer 1

','.join(list) will work only if all the items in the list are strings. If you are looking to convert a list of numbers to a comma separated string. such as a = [1, 2, 3, 4] into '1,2,3,4' then you can either

str(a)[1:-1] # '1, 2, 3, 4'

or

str(a).lstrip('[').rstrip(']') # '1, 2, 3, 4'

although this won't remove any nested list.

To convert it back to a list

a = '1,2,3,4'
import ast
ast.literal_eval('['+a+']')
#[1, 2, 3, 4]
