Remove trailing newline from the elements of a string list

You can either use a list comprehension my_list = [‘this\n’, ‘is\n’, ‘a\n’, ‘list\n’, ‘of\n’, ‘words\n’] stripped = [s.strip() for s in my_list] or alternatively use map(): stripped = list(map(str.strip, my_list)) In Python 2, map() directly returned a list, so you didn’t need the call to list.

This will be done for functions, classes, and external variables by using the following two compiler flags: -fdata-sections -ffunction-sections Link the translation units together using the linker optimization … Read more
