| Here are some samples to help get a better idea of Python's syntax: Hello World (the traditional first program) {{{#!python numbers=disable print 'Hello world!' # Python 2 syntax # or print('Hello world!') # Python 3 syntax }}} String formatting {{{#!python numbers=disable name = 'Monty' print('Hello, %s' % name) # string interpolation print('Hello, {}'.format(name)) # string formatting }}} Defining a function {{{#!python numbers=disable def add_one(x): return x + 1 }}} Testing variable equality {{{#!python numbers=disable x=1 y=2 print 'x is equal to y: %s' % (x==y) z=1 print 'x is equal to z: %s' % (x==z) names=['Donald','Jake','Phil'] words=['Random','Words','Dogs'] if names==words: print 'Names list is equal to words' else: print 'Names list isn\'t equal to words' new_names=['Donald','Jake','Phil'] print 'New names list is equal to names: %s' % (new_names==names) }}} Defining a class with two methods {{{#!python numbers=disable class Talker(object): def greet(self, name): print 'Hello, %s!' % name def farewell(self, name): print 'Farewell, %s!' % name }}} Defining a list {{{#!python numbers=disable dynamic_languages = ['Python', 'Ruby', 'Groovy'] dynamic_languages.append('Lisp') }}} Defining a dictionary {{{#!python numbers=disable numbered_words=dict() numbered_words[2]='world' numbered_words[1]='Hello' numbered_words[3]='!' }}} Defining a while loop {{{#!python numbers=disable while True: if value==wanted_value: break else: pass }}} Defining multiline strings {{{#!python numbers=disable string = '''This is a string with embedded newlines. Also known as a tripled-quoted string. Whitespace at the beginning of lines is included, so the above line is indented but the others are not. ''' }}} Defining long strings over multiple lines {{{#!python numbers=disable string = ('This is a single long, long string' ' written over many lines for convenience' ' using implicit concatenation to join each' ' piece into a single string without extra' ' newlines (unless you add them yourself).') }}} Defining a for loop {{{#!python numbers=disable for x in xrange(1,4): print ('Hello, new Python user!' 'This is time number %d') % (x) }}} ---- CategoryDocumentation |
