The function file_first_chars in python takes one parameter, fname, the name of a text file, and returns a string made up of the first character from each line in the file. You may assume there are no blank lines in the file.
Hint: Use a for loop to iterate over the lines of the file and accumulate the string of first characters.
NOTE: Return the function, don't print
For example:
Test
Result
print(file_first_chars("wordlist1.txt"))

In Python
Write a program that reads the contents of a text file and inserts the line numbers at the beginning of each line, then rewrites the file contents
Write a code segment that creates an ofstream object named outfile, opens a file named numbers.txt, and associates it with outfile. The code should then use a loop to write the numbers 1 through 100 to the file before closing it.
