I was working with some lists until I realize a weird behavior. I forgot to put a comma between items of the list. Then I got this:
my_list = ['foo', 'bar' 'xpto', 'qux']
>>> ['foo', 'barxpto', 'qux']
It took so long for me to realize that I forgot to put the comma there because the program doesn't threw any errors. So, why this happened? Why python concatenate the list items instead throwing an exception?
