In Lisp, data is code. Coincidentally, Lisp stands for LISt-Processing, and if you've ever seen a line of lisp (usually followed by "sweet mother of jesus what are all these parentheses?"), you'll know that lists are easy to express:. (In the off chance jAndy reads this: The Game). Hey, lists are pretty integral to every data manipulation, and we usually deal with trees, and Lisp data is already oriented towards tree-based structures. And when we really strip down all functionality of Lisp, we really just get an AST (Abstract Syntax Tree). hmm...I wonder where this will lead us to...

QUESTION
I'm a newbie... and studying about global
keyword.
This code creates a random string.
I think line 8, string.append(word[x])
make error on this code
because string
is a global variable, so must be required global
keyword. (global string)
But this code runs correctly... Why can run correctly...?
...ANSWER
Answered 2021-Jun-11 at 04:16Your code doesn't seem to have any problems at first look, although not very clear on what you want to be happening or the error, but in get()
, your list string
doesn't need to be assigned as a global variable unless you want to re-define the variable. If for whatever reason, you decide to declare string
or any variable in that matter inside a funcion, you would need to change its scope.

...ANSWER
Answered 2021-Jun-07 at 21:06writer.writerows()
takes a collection of rows as the first parameter. Since you pass a string (a collection of characters), each character of the string is treated as a separate row. Use writer.writerow()
instead.
writer.writerow()
, on the other hand, takes a collection of columns. Be sure to pass to it a list of columns, not a single string, as in writer.writerow([your_string])
.

...ANSWER
Answered 2021-May-30 at 18:07Every bidirectional association must have one owning side only (the child side), the other one being referred to as the inverse (or the mappedBy
) side. As @ManyToMany
association is symmetric, the owning side can be either one.
The @JoinTable
