a,b=b,a values swap ':'.join(['toto','12','pswd']) → 'toto:12:pswd'. a,*b=seq unpacking of sequence in str splitted on whitespaces → list of str. *a,b=seq item and list "words with spaces".split() → ['words','with','spaces'] x+=3 and increment ⇔ x=x+3 str splitted on separator str → list of str *=.
The keys method returns all keys in a dictionary, the values method returns all values in a dictionary and items method returns all key-value pairs in a dictionary. > a.keys() ['x', 'y', 'z'] > a.values() [1, 2, 3] > a.items() [('x', 1), ('y', 2), ('z', 3)] The for statement can be used to iterate over a dictionary.
