A bar code is a  series of bars and spaces representing numbers or letters.

<h3><u>Explanation:</u></h3>

A method that is used for the purpose of representing a data in the form of a picture or image that can be easily understood by the machine. It consists of many lines that has different widths and spaces. They either represent the letter or a number. These are mainly used for the representation of data in the machine understandable format.

For example an UPC-A bar codes has 12 numbers. The numbering system is represented by the first digit. The manufacturer will be represented by the next five digits in it. The product will be represented by the five digits following it. Check digit is represented in the last digit.

Write a function called st_dev. St_dev should have one #parameter, a filename. The file will contain one integer on #each line.
kodGreya [7K]

Answer:

  1. import statistics
  2. def st_dev(file_name):
  3.    with open(file_name) as file:
  4.        data = file.readlines()
  5.        numList = []
  6.        for x in data:
  7.            numList.append(int(x))
  8.        
  9.        return statistics.pstdev(numList)
  10. print(st_dev("text1.txt"))

Explanation:

The solution code is written using Python.

To ease the calculation task, we can import Python statistics module to use the pstdev method to calculate the population standard deviation of a list of numbers (Line 1).

Next, create a st_dev function that take single argument file_name (Line 3). In the function, it will open the input file and read the data line by line (Line 4-5). Create a for loop to traverse through each line of the data which is an integer and append it to numList (Line 7-8). We can pass the numList to pstdev method (Line 10) and return the resulting standard deviation value as output.

We test the function by passing a file which hold a list of integer values in each line (Line 12).

Until 1985, Tribhuvan University (TU) was the only university in the country. The second university to be founded was Mahendra Sanskrit University. The inception of this university was soon followed by Kathmandu University in 1990, and Purbanchal and Pokhara Universities in 1995 and 1996, respectively. Many schools and colleges are run privately but none of the universities in Nepal are private.
