This means that the equivalent of {exprlist} = {next_value} is executed for each item in the iterable. An interesting example that illustrates this: for i in range(4): print(i) i = 10 Output: 0 1 2 3 Did you expect the loop to run just once? 💡 Explanation: The assignment ...

After that, you’ll walk through some best practices for achieving the equivalent of passing by reference in Python.Remove ads Contrasting Pass by Reference and Pass by Value When you pass function arguments by reference, those arguments are only references to existing values. In contrast, when ...
``parse_int``, if specified, will be called with the string of every JSON int to be decoded. By default this is equivalent to int(num_str). This can be used to use another datatype or parser for JSON integers (e.g. float). ``parse_constant``, if specified, will be called with...
