- 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 :: (double colon) in Python when subscripting sequences?

- Is there a not equal operator in Python? - Stack Overflow
There's the != (not equal) operator that returns True when two values differ, though be careful with the types because "1" != 1 This will always return True and "1" == 1 will always return False, since the types differ Python is dynamically, but strongly typed, and other statically typed languages would complain about comparing different types There's also the else clause:

- The tilde operator in Python - Stack Overflow
In Python, conceptually, numbers use an arbitrary number of bits The implementation will allocate more space automatically, according to what is necessary to represent the number (For example, if the value would "fit" in one machine word, then only one is used; the data type abstracts the process of sign-extending the number out to infinity )
- Does Python have a ternary conditional operator? - Stack Overflow
Python is a syntax-rich language with lots of idiomatic tricks that aren't immediately apparent to the dabbler But the more you learn and understand the mechanics of the underlying system, the more you appreciate it
