Is there an equivalent to the C/C++ 'case' (or 'switch') statement
in Python?
No, just if/elif
However you can often achieve similar results with a dictionary:
def func1(v): return v
def func2(v): return v*2
switch = { 'val1': func1, # use a function for each value
'val2': func2,
'val3': lambda v: "this is three!" } # or use
lambda if preferred
val = raw_input("Value? (val1,val2,val3)")
This:
print switch.[val](val)
should be: print switch[val](val)
### which is equivalent to:
if val == 'val1': print func1(val)
elif val == 'val2': print func2(val)
elif val == 'val3': print "this is three"
HTH,
