python matplotlib legend linestyle '---'

I need a way to make matplotlib linestyle '---'. 3's of '-'.

character description
'-'       solid line style
'--'      dashed line style
'-.'      dash-dot line style
':'       dotted line style
etc.

I can see '-' and '--' in the list, but on the right up side, my legend comes up like " -- red dotted line" (If I write linestyle = '--'). I want '--- red dotted line' on my legend box

Is there any way I can make the legend show three dashes? Here's what I'm doing.

import matplotlib.pyplot as mpt

def main():
    mpt.title("hi")
    mpt.xlabel("x axis")
    mpt.ylim([0,50])
    mpt.xlim([0,10])
    mpt.ylabel("y axis")
    mpt.plot([1,2,3,4],[2,3,4,5],'r', linestyle = '???????')
    mpt.legend(["red dotted line"])
    mpt.show()

main()

Use mpt.legend(handlelength=3) and linestyle='--'

mpt.plot([1,2,3,4],[2,3,4,5],'r', linestyle='--')
mpt.legend(["red dotted line"], handlelength=3)
