using python

The last program will take in the name of a file from the user and calculate some basic information about it, before printing out all of the information and calculated details to the user.

For this part of the homework, you can assume that the filename provided will be valid, and that the data inside will be well-formatted (i.e., free of errors). Each line of the file will use the following format:

 Dog Breed Name,numBorn,numAdopted 

The dog breed name is guaranteed to be no more than 22 letters, and the numbers are guaranteed to be no higher than 9999 (four digits).

The information printed out to the screen must be the dog breed name, the number of dogs adopted, the number of dogs born, and the percentage of dogs adopted from those born. There must also be column headings printed at the top of the list. (See the sample output for an example.)

To make the task a bit simpler, you are allowed to use magic numbers, butonly when formatting a string. Other numbers (like which position the breed name is stored in, for example), must be made into constants.

Please enter the name of the file to open: hw6 dogs.txt Adopted / Born -- Percentage 305 /372 138 /438 1918 784 /815 127 /324 76/ 264 178 /200 47/74 41 / 297 355 /685 148 / 438 155 /224 183 / 228 96/ 204 58 /68 447 /623 197 /371 85/314 74 /192 76 /85 81 . 99% 31 . 51% 100.00% 96. 20% 39 . 20% 28 . 79% 89. 00% 63. 51% 13 . 80% 51 . 82% 33. 79% 69 . 20% 80.26% 4706% 85 . 29% 71. 75% 53. 10% 27.07% 38 . 54% 89 . 41% 94 . 92% 28. 74% 46 . 90% 42. 35% 72 . 83% 0?00% Ches.
