Normally when I want to do what you describe I want to
do it for several functions not just a single one.
You can use a dictionary to hold the function names and
pointers to the functions themselves and then call them
by indexing into the dictionary. This works for me:
def dothat(x,y):
print "x=", x, " y=", y
return
def doanother(x, y, z):
print "x=", x, " y=", y, " z=", z
return
xdict={'dothat': dothat,
'doanother': doanother}
s='dothat'
t=(1,2)
xdict[s](*t)
results in:
x= 1 y= 2
s='another'
t=(1,2, 3)
xdict[s](*t)
results in:
x= 1 y= 2 z=3

Hiho,
Having a string: "dothat"
and a tuple: (x, y)
1. What's the best way to build a function call like: dothat(x,y)?
Assuming dothat is def'd in the same module,
2. is: eval("dothat(x,y)", None, (('x', 100), ('y', 200)))
the right way to have it executed?
If dothat is def'd in another module:
3. what would be the right way to initialize the globals to pass to eval ?
TIA,
