What is spam, ham and egg in python and foo and bar in other programming language (solved)

Question

I also searched in google but could'nt understand a single word. They were stating something like metasyntetic variable and placeholder as I barely understand this type of english😅. Can anyone please please explain in simple words?

Answer 1

They're(generally) Nothing but a placeholder or metasyntetic variables (Sorry for using that english again)
Understand it as just variables in any code used for giving examples or using it in a place where you don't have names for variables.
Spam,ham,egg are also used for same purposes not only in python but also in other programming languages.
A simple example can be:
spam=5
print(spam)
