(Homework Solution): PYTHON Exercise 1 (100 pts) For this assignment, you will work with the data files provided in the "names"

PYTHON

Exercise 1 (100 pts)

For this assignment, you will work with the data files provided in the “names” folder in the files section of this class. These files contain national data on the relative frequency of given names in the population of U.S. births where the individual has a Social Security Number. For each year of birth YYYY after 1879, there is a comma-delimited file called yobYYYY.txt. Each record in the individual annual files has the format “name,sex,number,” where “name” is 2 to 15 characters, “sex” is M (male) or F (female) and “number” is the number of occurrences of the name. Each file is sorted first on sex and then on number of occurrences in descending order.

Write a Python program that iterates through all the data files in the folder and calculates the total number of occurrences of a given name. Your program should do the following:

Ask the user for a name they’re interested in

Go through all the data files and find every instance of that name, adding them up to a total

Display the total number of instances of the given name.

For example, for the name “Alejandro” your program should perform as follows

What name are you interested in? Alejandro
Alejandro has been used a total of 132243 times

Program.py

Program will iterate through all files in a directory and calculate occured names count

from pathlib import Path # import to find all files in a folder
#get all data files in F:\names\ folder
pathlist = Path(“F:\names\”).glob(‘**/*.txt’)
num_words = 0
search_name=input(“What name are you interested in?”) #input name
print(“Searching,Please wait …”)
for path in pathlist: # for loop to get single file
# because path is object not string
fname = str(path) #put file name in fname variable
# print(fname)
with open(fname, ‘r’) as f: #open file to read and get content of file in f variable
for line in f: # scan each line in file
words = line.split(“,”) # split line of words seperated with commas
for w in words: # loop through every words in words array and store in w variable
if search_name == w: # compare if the name to be searched is in w variable
num_words += 1 # if name found increase count

print(search_name,”has been used a total of”,num_words,”times”) #print message

$from pathlib import Path # import to find all files in a folder #get all data files in F:\names\ folder pathlist = Path( F : \names\). glob (**/*.txt) num words 0 search name=input (What name are you interested in?) #input name print (Searching, Please wait ...) for path in path1 ist: # for loop to get single file # because path is object not string fname- str (path) #put file name in fname variable # print (fname) with open (fname, r) as f: #open file to read and get content of file in f variable for line in f: # scan each line in file words line. split(,) # split line of words seperated with commas for w in words: # loop through every words in words array and store in w variable if search name == w: # compare if the name to be searched is in w variable num words +-1 # if name found increase count print (search name, has been used a total of,num words, times) #print message$
