how to get the highest monthly average temperature?

[nikhilkumar]

my question here
Create a program that reads from a file to display city name and average temperature in Celsius

use !curl to download https://raw.githubusercontent.com/Micros...p_mean.csv as mean_temp.txt

1) open the file in 'r' mode
2) read the first line of text into a variable called: headings and print()
3) convert headings to a list using .split(',') which splits on each comma, print() the list
4) use a while loop to read the remaining lines from the file
5) assign remainging lines to a city_temp variable
6) convert the city_temp to a list using .split(',') for each .readline() in the loop
7) print each city & the highest monthly average temperature
8)close mean_temps

!curl https://raw.githubusercontent.com/MicrosoftLearning/intropython/master/world_temp_mean.csv -o mean_temp.txt
mean_file=open("mean_temp.txt","r")
headings=mean_file.readline().strip('\n')
print(headings)
heading=headings.split(",")
print(heading)
city_temp=""
city_temp2=[]
headings2=mean_file.readline()
while headings2:
    city_temp+=headings2
    city_temp2.append(headings2.split(","))
    headings2=mean_file.readline()
    
print(city_temp)
print(city_temp2)
for city in city_temp2:
    print(city[0])

Output:

city,country,month ave: highest high,month ave: lowest low
['city', 'country', 'month ave: highest high', 'month ave: lowest low']
Beijing,China,30.9,-8.4
Cairo,Egypt,34.7,1.2
London,UK,23.5,2.1
Nairobi,Kenya,26.3,10.5
New York City,USA,28.9,-2.8
Sydney,Australia,26.5,8.7
Tokyo,Japan,30.8,0.9
