Suppose the following expressions are

used to calculate the values of $L$ for

different values of $S$ :

If $S<mn\; id="EditorElement\_1003430">1</mn><mn\; id="EditorElement\_1003431">0</mn><mn\; id="EditorElement\_1003432">0</mn>$ then calculate the value of $L$ using

the following equation:

L$-3000-125$S$^2$

if $S100$ then calculate the value of $L$ using

the following equation:

$L=\frac{120004+S^{{?}^{{?}^{?}}}2}{14900}$

Help me to write a Python code of a

program that reads a value of $S$ and then

calculates the value of $L.$

Help me to write a python program that

reads a number from the user and prints

the number is valid only if it is greater than

$100$ and is an even number.
