Python:

Write a program in a file called averageLength.py

This program asks the user for three strings and prints the average length of the strings entered.

Display only $2$ digits after the decimal point.

HINT: the average of three numbers is computed by adding the three numbers and dividing the result by $3.$

HINT: the length of a string is computed using the function len. Len$("$hello$")$ return $5$

Examples:

$\%$ python$3$ averageLength.py

enter first string: a

enter second string: b

enter third string: c

the average length is: $1\mathrm{.}00$

$\%$ python$3$ averageLength.py

enter first string: hello world

enter second string: hello world world

enter third string: hello hello world world

the average length is: $17\mathrm{.}00$

$\%$
