got a syntax error in line 177

I tried to run the program but had a syntax error in line 177:
ovhc = calculate_ovh(rtssfile, int(var1), int(var2), True)

the error:
ovhc = calculate_ovh(rtssfile, int(var1), int(var2), True)
                                                                   ^
SyntaxError: invalid syntax

I would appreciate if you could guide me to fix it.
