Data Analysis Bootcamp Guided Projects Datasimple Education Functions, in python, are first class objects which means you can pass a function as an argument to another function, and return functions. decorators do both of these things. if we stack decorators, the function, as defined, gets passed first to the decorator immediately above it, then the next, and so on. Python is dynamically, but strongly typed, and other statically typed languages would complain about comparing different types. there's also the else clause: # this will always print either "hi" or "no hi" unless something unforeseen happens. if hi == "hi": # the variable hi is being compared to the string "hi", strings are immutable in python.
Data Analysis Bootcamp Guided Projects Datasimple Education There is no bitwise negation in python (just the bitwise inverse operator ~ but that is not equivalent to not). see also 6.6. unary arithmetic and bitwise binary operations and 6.7. binary arithmetic operations. the logical operators (like in many other languages) have the advantage that these are short circuited. In python this is simply =. to translate this pseudocode into python you would need to know the data structures being referenced, and a bit more of the algorithm implementation. some notes about psuedocode::= is the assignment operator or = in python = is the equality operator or == in python ; there are certain styles, and your mileage may vary:. Since is for comparing objects and since in python 3 every variable such as string interpret as an object, let's see what happened in above paragraphs. in python there is id function that shows a unique constant of an object during its lifetime. this id is using in back end of python interpreter to compare two objects using is keyword. Running mac os high sierra on a macbookpro 15" python 2.7 pip 9.0.1 i tried both: sudo h pip install trusted host pypi.python.org numpy and sudo pip install trusted host pypi.python.org numpy it always gives me the same error: "there was a problem confirming the ssl certificate: [ssl: tlsv1 alert protocol version] tlsv1 alert protocol.

You must run python my script.py from the directory where the file is located. alternatively python path to my script.py. however, you can run python m my script (ie refer to the script by module name by omitting the .py) from anywhere, as long as python can find it! python searches as follows (not 100% sure about the order): current directory. I apologize if this is a silly question, but i have been trying to teach myself how to use beautifulsoup so that i can create a few projects. i was following this link as a tutorial: y. How python figures out missing parameters: when slicing, if you leave out any parameter, python tries to figure it out automatically. if you check the source code of cpython, you will find a function called pyslice getindicesex() which figures out indices to a slice for any given parameters. here is the logical equivalent code in python. In more detail, python 2.x has docstrings, which allow you to attach a metadata string to various types of object. this is amazingly handy, so python 3 extends the feature by allowing you to attach metadata to functions describing their parameters and return values. there's no preconceived use case, but the pep suggests several.
