[Python] Write a function named "total_population" that takes a string then a list as parameters where the string represents the name of a CSV file containing city data in the format "CountryCode,CityName,Region,Population,Latitude,Longitude" and the second parameter is a list where each element is itself a list containing 3 strings as elements representing the CountryCode, CityName, and Region in this order. Return the total population of all cities in the list. Note that the city must match the country, name, and region to ensure that the correct city is being read.

import csv
def total_population(CsvfleName,CityInformation):
TotalPopulation = 0
for CityInfoList in CityInformation:
CodeofCountry = CityInfoList[0]
NameOfCity = CityInfoList[1]
Region = CityInfoList[2])
with open (CsvfleName, newline='') as FileData:
ReadCsvFileData = csv.reader(FileData)
for line in readCsv:
if (line[0] == CodeofCountry):
if (line[1] == NameOfCity):
if ((line[2]) == Region):
TotalPopulation = TotalPopulation + int(line[3])
return TotalPopulation

Write a Python function first_chars that takes one parameter, which is a nested list of strings. It returns a string containing the first character of all of the non-empty strings (at whatever depth they occur in the nested list) concatenated together. Here are a couple of examples of how the function should behave when you're done: >>> first_chars(['Boo', 'is', 'happy', 'today']) 'Biht' >>>first_chars(['boo', 'was', ['sleeping', 'deeply'], 'that', 'night', ['as', ['usual']]]) 'bwsdtnau'

Write a function that takes, as an argument, a list, identified by the variable aList. If the list only contains elements containing digits (either as strings as integers), return the string formed by concatenating all of the elements in the list (see the example that follows). Otherwise, return a string indicating the length of the list, as specified in the examples that follow. Name this function AmIDigits(aList). For example, >>> AmIDigits([“hello”, 23]) should return the string “The length of the...
