- What does colon equal (:=) in Python mean? - Stack Overflow
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:
- Is there a not equal operator in Python? - Stack Overflow
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
- What is Pythons equivalent of (logical-and) in an if-statement?
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
- What is the reason for having in Python? [duplicate]
In Python 3, they made the operator do a floating-point division, and added the operator to do integer division (i e , quotient without remainder); whereas in Python 2, the operator was simply integer division, unless one of the operands was already a floating point number In Python 2 X:
- python - What is the purpose of the -m switch? - Stack Overflow
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
- What is :: (double colon) in Python when subscripting sequences?
When slicing in Python the third parameter is the step As others mentioned, see Extended Slices for a nice overview With this knowledge, [::3] just means that you have not specified any start or end indices for your slice Since you have specified a step, 3, this will take every third entry of something starting at the first index For example:
- math - ` ` vs ` ` for division in Python - Stack Overflow
In Python 2 2 or later in the 2 x line, there is no difference for integers unless you perform a from __future__ import division, which causes Python 2 x to adopt the 3 x behavior Regardless of the future import, 5 0 2 will return 2 0 since that's the floor division result of the operation
- What does the percentage sign mean in Python [duplicate]
It's an operator in Python that can mean several things depending on the context A lot of what follows was already mentioned (or hinted at) in the other answers but I thought it could be helpful to provide a more extensive summary % for Numbers: Modulo operation Remainder Rest The percentage sign is an operator in Python It's described as:
