@slelievre Thank you, I still need 50 rep points to do so.

Here's how I figured it out on Windows 10 with SageMath 9.1, for any future persons confused by this.

1. I decided to put my Sage scripts in the folder C:\scripts\sage.

2. I added this path to Sage's load attach path so Sage knows where to look. I did this in the console with

   sage: load_attach_path('C:\\scripts\\sage')

3. To load eaxmple.sage from the above directory, I can now simply use

   sage: load('example.sage')

Suppose you have two numbers which are already expressed in binary, and you want to do some arithmetic with them. How do you tell Sage that the strings you're inputting are already expressed in base $2$, and you would like the output to also be in base $2$. For example, I'd like something that works like this

sage: 10010 + 1010
sage: 11100

but I can't figure out how to tell Sage I wish to work in base $2$, or more generally, base $b$.

Suppose you're working with the sage console primarily as a calculator, and define some temporary shorthand function, such as,

sage: R = GF(751)
sage: def f(x):
....:    return R(x^3-x+188)

After I've used this f several times, I may want to change the output to something similar, like x^3-x+376. Is there a quick way to recall the definition of f within the console so that I can edit in the minor change, instead of having to define a new function?

Suppose $f$ is a function from some set to itself. Is there a shortcut command in sage to compute an iterated composition of $f$, such as $f^3(x)=f(f(f(x)))$ where I could type something like f^3(x) into the console, and more generally for computing $f^n(x)$ for a given $n$?

I am trying to follow the Loading and Attaching Sage files tutorial. I am working on Windows 10. I created an example.sage file by simply writing a .txt file and changing the extension to .sage, and put it on my desktop, located at

C:/Users/vika/Desktop/example.sage.

In the SageMath 9.1 Console, I get the following issues depending on the type of slash

sage: load("C:/Users/vika/Desktop/example.sage")
OSError: did not find file 'C:/Users/vika/Desktop/example.sage' to load or attach
sage: load("C:\Users\vika\Desktop\example.sage")
SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in position 2-3: truncated \UXXXXXXXX escape

Where am I supposed to put this file in order to load it? I know that sage is installed at C:/Users/vika/AppData/Local/SageMath 9.1 if that matters.
