simple string assignment
>>> var1 = 'foo'
this automatically creates a variable of type string
>>> type(var1) <type 'str'>
printing your variable...
>>> print var1 foo
string assignment like above must be incapsulated by quotes or the right side is interpretted as a variable name.
example:
>>> var1 = foo Traceback (most recent call last): File "<stdin>", line 1, in ? NameError: name 'foo' is not defined
integar variable
>>> my_int_var1 = 1 >>> print my_int_var1 1
print sing variable named foo
>>> print foo
print multiple variables with text
print 'my variable are %s %s' % (FOO, BAR)
Common string operations
print nth word of string
print s.split()[n]
