For Python 3.3 Ask the user to input a line of text with the prompt "Enter a string: ". The program should extract all numbers (either with a decimal point our without one) from the line of text, compute their sum, and print it as a floating point number with two places to the right of the decimal point. (To print the floating point variable ff with exactly two decimal places use print('%.2f' % ff)

For example, if the input was The sum of 246 and 1025 is the output should be the single line 1271.00

If the input is Fried oysters $12.75, salad $3.35, coffee $1.85, tax 1.36 the output should be 19.31

And if the input is dyuadgh12345agdfkl;j12 the output should be 12357.00
