What is the replacement of Switch Case in Python ?
Unlike every other programming language we have used before, Python does not have a switch or case statement. To get around this fact, we use dictionary mapping.
# Function to convert number into string # Switcher is dictionary data type here def numbers_to_strings(argument): switcher = { 0: "zero", 1: "one", 2: "two", } # get() method of dictionary data type returns # value of passed argument if it is present # in dictionary otherwise second argument will # be assigned as default value of passed argument return switcher.get(argument, "nothing") # Driver program if __name__ == "__main__": argument=0 print numbers_to_strings(argument) |
This code is analogous to given code in C++ :
#include<bits/stdc++.h> using namespace std; // Function to convert number into string string numbers_to_strings(int argument){ switch(argument) { case 0: return "zero"; case 1: return "one"; case 2: return "two"; default: return "nothing"; }; }; // Driver program int main() { int argument = 0; cout << numbers_to_strings(argument); return 0; } |
Output:
Zero
