"no variable or argument declarations are necessary."

I am contemplating getting into Python, which is used by engineers I
admire - google and Bram Cohen, but was horrified to read
"no variable or argument declarations are necessary."
Surely that means that if I misspell a variable name, my program will
mysteriously fail to work with no error message.
If you don't declare variables, you can inadvertently re-use an
variable used in an enclosing context when you don't intend to, or
inadvertently reference a new variable (a typo) when you intended to
reference an existing variable.
What can one do to swiftly detect this type of bug?
