Aligning Floating Point with format()

Project: Aligning Floating Point with format()

Write a program that demonstrates floating point formatting using default (most compact), fixed point and exponential (scientific) formats using format() style output. Print using no precision, precision of 2 and a field width of 10 with precision 2. Your program should reproduce the output shown using the following variables:

π = 3.141592653589793
𝑒 = 2.718281828459045
avogadro = 6.0221412927e23
electron_mass = 9.1093821545e-31

Output
