In RStudio the following code will return 3 2 when I use the dim function. Can someone explain to me step-bystep how RStudio gets to the following result? dfch <- data.frame( "City" = c("St.Gallen", "Lausanne", "Zürich" ), "PartyLeft" = c(35, 45, 55), "PartyRight" = c(40, 35, 30) ) dim(dfch[ , dfch$PartyLeft > 40] Also when we use dfch[ , dfch$PartyLeft > 40 ] returns a 3x2 matrix with column PartyLeft and PartyRight. How does RStudio proceed to get to that answer?

def reverse_sentence(s: str) -> str:"""This means that in the string 'ATest string!', there are in fact only twowords: 'A' and 'Test string!'.

I am making a program that works with a CSV file with three columns: names, cities, and heights. I'm trying to find the person with the most average height in their city. I found the average, but I need to create a difference table to find the person whose height is closest to the average. import csvdata = []with open("C:\\Users\\lucas\\Downloads\\sample-data.csv") as f: reader = csv.reader(f) for row in csv.reader(f): data.append(list(row)) f.close()data.pop(0)# print(data) city_list = []for i in range(len(data)): city_list.append(data[i][1])city_list.sort()print(city_list) unique_cities = []people_count = []for city in city_list: # this if statement analyzes which cities are in unique_cities.

Can you please exlain step by step .Thank you
I have a program that asks for queries. It is based on a CSV file with three columns for a person's name, city, and height. The print statement for City_list gives it a blank. The problem I'm running into is that if I insert a city that isn't in the CSV file, it ends and doesn't transition to other cities. When I do put in the city that is in the list, it prints out the indexes from the file. How can this be revised to ignore off-list cities and work with in-list cities?
