Hi
I'm trying to create a script that automatically sets the timeline range to the animation range of a selected camera.
I track my cameras in nuke using DPXs sequences created from the original ARRIRAW files. so its animation range is based on the frame range of the clip.
So when i import the camera into maya, the animation doesnt start from 1, its whatever the frame range was so could be 19567-20111 for example.

I've been trying to create a python script using this as my base,

import maya.cmds as cmds
firstKey = cmds.keyframe("camera1.translateX", index=(0,0), query=True);
print firstKey

and i get
19567.0

and i know i can manually alter the animation start time using 

playbackOptions -ainmationStartTime 19567;

but when i try and patch one into the other im getting the error

Invalid arguments for flag 'ast'.  Expected time, got [ float ],

So how can i convert my returned float value, from the first command, into a time ( i assume as i could just type in 19567, all it actually needs is an integer, not a float.)

Thanks

Andy

You need to provide time in the format supported by the command flag. In this case, time is represented as an integer. To convert a float to an integer, use the builtin int() function. This rounds toward zero. If you wish to round the number instead, use the round() builtin. 

>>> timeVar = 10.0
>>> timeVar = int(timeVar)
 
cmds.playbackOptions(ast=timeVar)

Method int() is the Python standard built-in function to convert a string into an integer value. You call it with a string containing a number as the argument, and it returns the number converted to an actual integer....Python string to int33
