Obvious. x, _ = func() x, junk = func() Hideous. x = func()[0]
  • It works with virtualenv for Python 3 and 2 and also for the venv module in Python 3: import sys def is_venv(): return (hasattr(sys, 'real_prefix') or (hasattr(sys, 'base_prefix') and sys.base_prefix != sys.prefix)) The check for sys.real_prefix covers virtualenv, the equality of non-empty sys.base_prefix with sys.prefix covers venv.
  • Return Value. Python's any() and or return different types of values. any() returns a Boolean, which indicates whether it found a truthy value in the iterable: >>> >>> any ((1, 0)) True. In this example, any() found a truthy value (the integer 1), so it returned the Boolean value True.

    This will work equally well under Python 2.6 as Python 3, although you get a one character str-string in Python 2.6 and a one character bytes-string in Python 3. However, under Python 2.5 or earlier, the b'GIF89a' syntax doesn’t work at all, so it’s only a solution if you don’t need to support versions of Python before 2.6.

    There are several data types in python. Lets take a look at the data types in python. Every value that we declare in python has a data type. Data types are classes and variables are the instances of these classes. Data Types In Python. According to the properties they possess, there are mainly six data types in python.

I'm a non-Python programmer, but to me the third variant makes the most sense. In variant 3 you are absolutely clear which values your are interested in dealing with. In variant 1 and 2, you are assigning the values back to variables, and thus, they can be used. You may have named them obscurely, but poor naming isn't really a solution to any ...
For values of immutable data types such as strings, integers, or tuples, Python variables will store the value itself. Although Python variables technically contain references to list or dictionary values, people often casually say that the variable contains the list or dictionary.
