Python Question:

Question 12

Write a function named fileStats. The function fileStats takes two string parameters: inFile, the name of an input file and outFile, the name of an output file.

The function fileStats should read and analyze the contents of the input file and write the statistics it compiles to the output file. The statistics you should compute about the input file are:

the number of characters;

the number of words;

the number of lines;

the number of digits;

the number of punctuation marks

Each statistic should be written to a separate line of the output file. (Hint: the string class contains constants named punctuation and digits.)

For example, if the input file contains the following lines:

Lord I'm one, Lord I'm two, Lord I'm three, Lord I'm four,

Lord I'm 500 miles from my home.

500 miles, 500 miles, 500 miles, 500 miles

Lord I'm five hundred miles from my home.

Then an output file with the following lines would be correct:

characters 181

words 35

lines 4

digits 15

punctuation 15

Question 13

Write a function named symmetry that takes a string, text, as a parameter and returns a dictionary d. Every letter that is both the first and last letter of some word in text should be a key in d. For example, if text contains the word 'shucks', 's' should be a key in d. The value of 's' in d is the number of words that both begin and end with 's'. The parameter text contains only upper and lower case characters and white space.

The following is an example of correct output:

t = '''The sun did not shine

it was too wet to play

so we sat in the house

all that cold cold wet day

I sat there with Sally

we sat there we two

and I said how I wish

we had something to do'''

print(symmetry(t))

{'d': 1, 'i': 3, 't': 1}

Explanation / Answer

12 : I have used punctuations and digits from string. Code :

from string import punctuation
from string import digits

def fileStats(inFile,outFile):
   chars = words = lines = punct = digit = 0
   #opening the file
   with open(inFile, 'r') as in_file:
       #reading the file line by line
   for line in in_file:
   lines += 1
   words += len(line.split())
   chars += len(line)
   #iterating over line to see if each character is in punctuation or digits.
   for c in line :
       if c in punctuation :
           punct+=1

       if c in digits :
           digit+=1

   f = open(outFile, 'w')

   f.write('characters :'+str(chars))
   f.write(' ')

   f.write('words :'+str(words))
   f.write(' ')

   f.write('lines :'+str(lines))
   f.write(' ')

   f.write('digits :'+str(digit))
   f.write(' ')

   f.write('punctuations :'+str(punct))
   f.write(' ')

   f.close()

fileStats('inputFile.txt','outputFile.txt')

Sample Input(inputFile.txt) :

Hey..!!
Whats up?
How you doing!?
123 555

Sample Output (outputFile.txt) :

characters :41
words :8
lines :4
digits :6
punctuations :7

13 : adding code with comments.

def symmetry(text) :

   #creating dictionary
   symmetry_dict = {}

   #iterating over each word
   for word in text.split() :
       #saving firstletter of word
       firstLetter = word[0]
       #checking if this word ends with this letter
       if (word.endswith(firstLetter)) :
           #check if firstLetter is present in dict
           #if it does add its counter
           #else insert in dict
           if firstLetter in symmetry_dict :
               symmetry_dict[firstLetter] += 1
           else :
               symmetry_dict[firstLetter] = 1

   return symmetry_dict

t ="Write a function named symmetry that takes a string, text, as a parameter and returns a dictionary d. Every letter that is both the first and last letter of some word in text should be a key in d"
print(symmetry(t))

Sampe output :

{'a': 5, 't': 3, 'd': 1}
