- 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:
- 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 - Is there a difference between == and is? - Stack Overflow
According to the previous answers: It seems python performs caching on small integer and strings which means that it utilizes the same object reference for 'hello' string occurrences in this code snapshot, while it did not preform caching for 'hello sam' as it is relatively larger than 'hello' (i e it manages different references of 'hello sam
- math - ` ` vs ` ` for division in Python - Stack Overflow
In Python 3 x, 5 2 will return 2 5 and 5 2 will return 2 The former is floating point division, and the latter is floor division, sometimes also called integer division 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
- python - What is the purpose of the -m switch? - Stack Overflow
Python 2 4 adds the command line switch -m to allow modules to be located using the Python module namespace for execution as scripts The motivating examples were standard library modules such as pdb and profile, and the Python 2 4 implementation is fine for this limited purpose
- python - What exactly does += do? - Stack Overflow
I need to know what += does in Python It's that simple I also would appreciate links to definitions of other shorthand tools in Python
- Behaviour of increment and decrement operators in Python
Python is not C or C++ Different design decisions went into making the language In particular, Python deliberately does not define assignment operators that can be used in an arbitrary expression; rather, there are assignment statements and augmented assignment statements See reference below
