Many languages have these challenges. Some ideas:

As mentioned in the comments, tack an underscore on the end: from_
Add context or type (also mentioned in comments): from => from_list
Mangle the spelling (from => frm, e.g. class => klass or cls)
Use a synonym: from => source

Each approach has its advantages and disadvantages.
I want to use name from for an argument of a function. But from is a reserved keyword, so python will throw an exception if I decide to use this name for a variable.
How programmers in python deal with it? I think from is a common name for variables, in python as well. Is there any standards in python for how to rename the argument/variable in this case? Do they use prefixes/suffixes like from_?
How do python programmers deal with inability to use reserved keywords as names for variables in python (like`from`)?
