$1-$ Problem description: Pendulum

Figure $1.$ Pendulum

Pendulum, is a body suspended from a fixed point on a string so that it can swing back and forth under the influence of gravity.

A cycle of a pendulum is when we pull it back then we release it$,$ the pendulum will swing out then swing back and that's called one cycle. Period $(T)$ is the time it takes the pendulum to complete one cycle, while the frequency $(F)$ is the number of cycles the pendulum completes in one second which is $F=\frac{1}{T}.$

The period is measured in seconds according to the following equation.

$T=2\sqrt[\phantom{2}]{\frac{L}{g}}$

Where

$L=$ is length of the string in meters

$g=$ Acceleration gravity

For example, on Mars the acceleration gravity is $3\mathrm{.}71$ and if the length of the string is $70cm$ then the period equals $2\mathrm{.}73,$ and the frequency is $0\mathrm{.}37$

$2-$ Programming task:

Write a python program that:

Display list of planets shown in table $1,$ asking about which planet the user wish to generate the values of period and frequency.

Make sure the length of the string $L$ is $>0.$

Declare the suitable constants.

Generate formatted output as shown in sample runs Figure $2$ for different planets in the solar system calculating the period and the frequency of the pendulum experiment for a specific planet using Table $(1)$ information.
