Python string, numeric calculation

Python is an object-oriented language, but it does not encapsulate standard classes like C + + into libraries, but instead encapsulates them in a further way, and the language itself integrates classes and functions such as print,list,dict etc. Great convenience for programming

Python uses # for a single-line comment, using "or" "for multiline comments

Numerical calculation

>>> print "One Hour has", "seconds" one hour have 3600 seconds>>> result = 12 # The same line of code uses a space segment to make the format more Clear >>> Print result12
