No, python's equivalent of Perl's foreach is "for". I.e.

    foreach $var (@list)

does the same thing as Python's

    for var in list

(except Perl gets the scoping right).

Maybe you're thinking of Perls "default variable" feature (I don't
know what else to call it), which implicitly uses $_ as a variable in
any number of places if you fail to provide a variable? So that you
can say:

   foreach (@list)

and apparently not have to use a variable,  except it implicitly uses $_.
