Exceptions python

Exceptions Errors detected during execution are called exceptions. Examples: ZeroDivisionError This error is raised when the second argument of a division or modulo operation is zero. >>> a = '1' >>> b = '0' >>> print int(a) / int(b) >>> ZeroDivisionError: integer division or modulo by zero ValueError This error is raised when a built-in operation or function receives an argument that has the right type but an inappropriate value. >>> a = '1' >>> b = '#' >>> print int(a) / i

Class 2 - Find the Torsional Angle python

You are given four points A,B,C and D in a 3-dimensional Cartesian coordinate system. You are required to print the angle between the plane made by the points A,B,C and B,C,D in degrees(not radians). Let the angle be PHI. Cos(PHI) = (X.Y) / |X| |Y| where X=AB x BC and Y= BC x CD. Here, X.Y means the dot product of X and Y, and AB x BC means the cross product of vectors AB and BC. Also, AB = B-A. Input Format One line of input containing the space separated floating number values
