I've been doing some work with large ints, of well over 100 digits. For example, this number has 131 digits: P = 29674495668685510550154174642905332730771991799853043350995075531276838753171770199594238596428121188033664754218345562493168782883 Sometimes I'm tempted to write numbers like that as follows: P = int('29674495668685510550154174642905332730771991' '79985304335099507553127683875317177019959423' '8596428121188033664754218345562493168782883') which is nicer to read, except for the minor annoyance of the call to int and the string delimiters. That got me thinking that it might be Nice To Have if we could split long int literals across multiple lines: P = 29674495668685510550154174642905332730771991\ 79985304335099507553127683875317177019959423\ 8596428121188033664754218345562493168782883 Or if you don't like backslashes, trailing underscores are currently illegal, so we could use them: P = 29674495668685510550154174642905332730771991_ 79985304335099507553127683875317177019959423_ 8596428121188033664754218345562493168782883 Thoughts? -- Steven
