Ever thought about writing a script which prints its own name when you execute it. It’s pretty simple. You must have noticed programs in which the main function is written like this
int main(int argc, char** argv)
and you must have wondered what these 2 arguments mean.
- Well the first one argc is the number of arguments passed in to your program.
- The second one argv is the array which holds the names of all the arguments passed into your program.
- Along with those arguments there is an extra piece of information stored in the array first cell of that array i.e. argv which is the full path of the file containing the code.
To print the name of the program all we need to do is to slice the filename out of that path.
Below is the python implementation of the idea discussed above. Let’s suppose the name of the script is print_my_name.
Note: The output will vary when you run it on GeeksforGeeks online compiler.
