如何根据列表中的项目要求输入？

Question

I'm trying to make a loop that asks for the rainfall of each month, with the months stored into a list. How can I make 1 loop that will ask for input of the rainfall for each month by pulling each month from the list?

example:

months = ["January", "February", "March"]
rainfall = input("What is the rainfall for ", months[0])

how can i do that for each month with 1 loop?

Answer 1

months = ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']
rainfall = []
for month in months:
    answer = int(input("What was the rainfall in {}?".format(month)))
    rainfall.append(answer)

Answer 2

I think you are asking about string formatting. There are several ways ( % , .format() , and f-strings), but my favorite would be .format() which would look like:

months = ["January", "February", "March"]
rainfall = input("What is the rainfall for {}".format(months[0]))

Then to repeat the process for all months would could look something like this:

months = ["January", "February", "March"]
rainfall = [input("What is the rainfall for {}?\n>>>".format(month)) for month in months]

Where I added some nice formatting with a \\n newline character, and an obvious prompt of >>>

Answer 3

You can use a for loop and a list that will keep taken rainfall answers from user. This will loop for all elements in months list.

months = ["January", "February", "March"]
rainfalls = []
for month in months:
    rainfall = input("What is the rainfall for " +  month+ "\n")
    rainfalls.append(rainfall)
print(rainfalls) #python3
