But this doesn’t prevent you from achieving the same results you’d expect when passing arguments by reference in other languages. In this course, you learned: How Python handles assigning values to variables
You even surpassed the elegance of Int32.TryParse() in C# thanks to Python’s flexibility! If you need to operate on multiple values, then you can write single-purpose functions that return multiple values, then (re)assign those values to variables. Here’s an example: Python def greet(...
Programming in Python 1.7.2 Passing by object In C++ you may have heard the terms ‘pass by value’ or ‘pass by reference’ with respect to how arguments are passed to functions. This references how variables are either copied to a new place in memory when they are passed to a function...
Example Pass a string by reference: voidmodifyStr(string &str) { str +=" World!"; } intmain() { string greeting ="Hello"; modifyStr(greeting); cout <<greeting; return0; } Try it Yourself » Exercise? True or False: Passing a variable by reference allows a function to modify its...

I am from c++ background. Pass by value and pass by reference are pretty clear in c++ because of &operator but in python I am confused how to pass object so that I can c
Now with strings in python it is very hard to see how this is different from other languages as. What do I mean by that? Consider the following example: var1="I am a string"var2=var1print(var1)print(var2)var2=var2+"!!"print(var1)print(var2) ...
