Question

The code is in C programming language pls convert it into python. Thanks.

Program -->

#include <stdio.h>

#include <stdlib.h>

void main()

{

//declare variables

FILE *fileptr;

char filename[15];

char charRead;

char filedata[200],searchString[50];

int i=0,j=0,countNoOfWord=0,count=0;

//enter the filename to be opened

printf("Enter the filename to be opened \n");

scanf("%s", filename);

/* open the file for reading */

fileptr = fopen(filename, "r");

//check file exit

if (fileptr == NULL)

{

printf("Cannot open file \n");

exit(0);

}

charRead = fgetc(fileptr);

//read the string from file

while (charRead != EOF)

{ filedata[i]=charRead;//store the file data in a string filedata variable

printf ("%c", charRead);

charRead = fgetc(fileptr);//get data from file

i++;

  

}

//count the total no of word in a file

for (j = 0;filedata[j] != '\0';j++)

{

if (filedata[j] == ' ')

countNoOfWord++;   

}

strlwr(filedata);//convert string into lower case

  

printf("\nnumber of words in given string are: %d\n", countNoOfWord );

fclose(fileptr);

//enter the word u want to count

printf("Enter word to count: \n");

scanf("%s", searchString);

//call function countOccuranceOfWord to count the word which return integer of no of words

count = countOccuranceOfWord(filedata, searchString);

printf("Total occurrences of '%s': %d \n", searchString, count);

//write into file output.txt

fileptr = fopen("output.txt", "w");

if(fileptr == NULL)

{

printf("Error!");

exit(1);

}

char sentence1[50]="Total no. of words";

char sentence2[50]="Total occurrences of ";

//writing into output.txt

fprintf(fileptr,"%s %d %s %s %d", sentence1,(countNoOfWord),sentence2,searchString,count);

fclose(fileptr);//close fileptr

  

}

//function to countOccurance of word

int countOccuranceOfWord(char * str, char * toSearch)

{

int i, j, found, count;

int stringLen, searchLen;

stringLen = strlen(str); // length of string

searchLen = strlen(toSearch); // length of word to be searched

count = 0;

for(i=0; i <= stringLen-searchLen; i++)

{

/* Match word with string */

found = 1;

for(j=0; j<searchLen; j++)

{

if(str[i + j] != toSearch[j])

{

found = 0;

break;

}

}

if(found == 1)

{

count++;

}

}

return count;

}

Answer 1

filename = input("enter the file name:")
f = open(filename,'r')
paragraph = f.read()
countnowords = 0
for i in range(0,len(paragraph)):
   if(paragraph[i] == ' ' or paragraph[i] == '.' or paragraph[i] == '\n'):
       countnowords += 1

count_string = input("enter the string to count:")
no_of_occurences = paragraph.count(count_string)

f.close()
f = open("output.txt","w")
f.write("Total no of words : {} \n Total no of occurences of {} is {}".format(countnowords,count_string,no_of_occurences))
f.close()
