- 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
- 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
- slice - How slicing in Python works - Stack Overflow
In Python 2 7 Slicing in Python [a:b:c] len = length of string, tuple or list c -- default is +1 The sign of c indicates forward or backward, absolute value of c indicates steps Default is forward with step size 1 Positive means forward, negative means backward a -- When c is positive or blank, default is 0 When c is negative, default is -1
- Behaviour of increment and decrement operators in Python
Python does not have unary increment decrement operators (-- ++) Instead, to increment a value, use a += 1 More detail and gotchas But be careful here If you're coming from C, even this is different in python Python doesn't have "variables" in the sense that C does, instead python uses names and objects, and in python ints are immutable
