hello, i need help with writing a python code using python 3.6 to solve for inpute impedance at any point in transmission line

Inputs are zi (normalized load impedance) and (in wavelengths) Output is Zin Relevant equation [2.79] Your code must be able to accept any values of z Your code must prompt the user for Zin and l (complex, normalized) and length e You are to run the following four cases to solve for Zin The results must be clearly displayed in your assignment
