Experimenting with magic methods (__sizeof__ in particular) on different Python objects I stumbled over the following behaviour:
I don't come from a software/computer science background but I love to code in Python and can generally understand why things are faster. I am really curious to know why this for loop runs faster than the dictionary comprehension. Any insights?
I understand dictionaries are insertion ordered in Python 3.6+, as an implementation detail in 3.6 and official in 3.7+.
I understand that conditional expressions (or ternary operators) are lazy in Python. They represent conditional execution rather than conditional selection. In other words, only one of a or b is evaluated in the following:
I know, that the purpose of str() method is to return the string representation of an object, so I wanted to test what happens if I force it to make something else.
There are a couple of ways to construct a dictionary in python, for example:andWhen you benchmark these
We already know that Function arguments used to have the limit of 255 explicitly passed arguments. However, this behaviour is changed now and since Python-3.7 there's no limit except sys.maxsize which is actually the limit of python's containers. But what about the local variables?
I think my question is related to this, but not exactly similar. Consider this code:The output of this code is:
What is the default encoding used for encoding strings in python 2.x? I've read that there are two possible ways to declare a string.
