combining strings to call a variable, possible?

[sam williams]

Hi there!,

say i have 10 curves in my maya scene. "curve1", "curve2", "curve3" and on.....,  and i have a variables curve1, curve2, curve3  which will be storing specific curves in the scene

i was wondering is there a way of calling the variable curve1 curve2 and curv3 in a loop by constructing two strings to create the variable, like this:

num=1

curve1="curve2"

curve2="curve4"

curve3="curve6"

while num<=3:

    currentCurve="curve" + str(num)

    print currentCurve

    num+=1

now this doesnt work, it prints curve1, curve2, curve3. - where i need it to print curve2, curve4, curve6

you see what i mean kind of?.

so its just about calling a variable, but first construcing the variable name with two strings. is this at all possible in python??

thanks alot, 

Sam

You’ll need to use locals() which is a built-in dictionary of all previously declared variables.

curve1="curve2"
curve2="curve4"
curve3="curve6"

print locals()['curve1'] == "curve2"  # Prints True

locals() documentation

Though as enrac5 says, you are probably better off using a look-up table (i.e. a dictionary).

curves = {'curve1': 'curve2',
          'curve2': 'curve4',
          'curve3': 'curve6'}
print curves['curve1'] == 'curve2' # Prints true
