Exercise 6.8: Make a nested dictionary from a file The viscosity u of gases depends on the temperature. For some gases the following formula is relevant: To -C (T\15 To - C µ(T) = HoT+C (T, where the values of the constants C, To, and Ho are found in the file src/ dictstring/viscosity_of_gases.dat". The temperature is measured in Kelvin. a) Load the file into a nested dictionary mu_data such that we can look up C, To. and lo for a gas with name name by mu_data[name] [X], where X is 'C' for C, 'T_0' for To, and 'mu_0' for µo- b) Make a function mu (T, gas, mu_data) for computing p(T) for a gas with name gas (according to the file) and information about constants C, To, and µo in mu_data. c) Plot u(T) for air, carbon dioxide, and hydrogen with T e [223, 373].
