Well can't do it for you but try using that phrase argument with string compare functionality
Set your camera up on a tripod
Choose a subject (anything really)
Get your camera up close to the subject
Switch your camera to Manual focus. You can try auto focus, but generally you will be able to focus a little closer on manual focus.
(If you are using manual focus, the tripod will be important.)
The Programmer wants to overload operators rather than use a regular member of the functions to perform similar operations because of two main reasons:
1. For easy and simpler definition of the functions. There would be one pointer who will call the function every time is needed in the program.
2. For easier comparisons of parameters.
In Python, a string is an array of characters, we can access these characters using index operator []. For example, we have a_string = "Hello World" a_string[0] prints the first character in string ('H').
We can also use index operator to make substrings, for example a_string[0:3] will make a substring with first, second, third and fourth character equal to "Hell".
Now to business
my_string = "This is MY string!"
print(my_string[0:7]) # Prints "This is "
print(my_string[0:7:5]) # Prints "T" then prints the sixth character since we start counting at 0 hence prints "Ti" (note that space is also a character).
Hope this helps.
