  • 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
    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:
  • slice - How slicing in Python works - Stack Overflow
    Python slicing is a computationally fast way to methodically access parts of your data In my opinion, to be even an intermediate Python programmer, it's one aspect of the language that it is necessary to be familiar with

  • python - Iterating over a dictionary using a for loop, getting keys . . .
    Why is it 'better' to use my_dict keys() over iterating directly over the dictionary? Iteration over a dictionary is clearly documented as yielding keys It appears you had Python 2 in mind when you answered this, because in Python 3 for key in my_dict keys() will still have the same problem with changing the dictionary size during iteration
  • What does [:-1] mean do in python? - Stack Overflow
    Working on a python assignment and was curious as to what [:-1] means in the context of the following code: instructions = f readline()[:-1] Have searched on here on S O and on Google but to no avail
  • Whats the difference between pip install and python -m pip install . . .
    By using python -m pip install --upgrade pip, or py -m pip install --upgrade pip instead, the problem is avoided, because now the wrapper executable does not run - Python (and possibly also py) runs, using code from the pip py (or a cached pip pyc) file
