Assume that a file containing a series of cities (as strings) is named cities. txt and exists on the computer’s disk. Write a program that displays the number of names that are stored in the file. (Hint: Open the file and read every string stored in it. Use a variable to keep a count of the number of items that are read from the file.)

name = 'cities.txt'

obj = open(name, 'r')

ctr = 0

for l in obj:

   ctr += 1

print('Total ', ctr, ' names in this file.')

obj.close()

Explanation:

the answer to your question would be something called hertz. the unit of measurement called a hertz, which is one cycle per second, is used to measure clock speed. within one cycle, your computer processes, refreshes, or updates itself to the changes that it is going through. in the case of computer clock speed, one hertz equals one tick per second. the clock speed of computers is usually measured in megahertz (mhz) or gigahertz (ghz)
