It kinda depends a bit upon your script, and target rate.
Code:
ChangeFPS(25.0) # 25 FPS, with default special un-named implicit Last clip as source, implied assign result to special Last clip
ChangeFPS(24000,1001) # 23.976 FPS (numerator,denominator)
# ...
src.ChangeFPS(25.0) # 25 FPS, with named source clip, implied assign result to special Last clip
src.ChangeFPS(24000,1001) # 23.976 FPS (numerator,denominator)
# ...
dst = src.ChangeFPS(25.0) # 25 FPS, with named source clip, and assign to dest clip
dst = src.ChangeFPS(24000,1001) # 23.976 FPS (numerator,denominator)
