I'm trying to put multiple interest rates from one input into a list. I'm assuming just putting a comma between them wont separate them into different variables in the list? Is there a way I can get them all into a list in one input or do i need to run the input multiple times and add one each time?
interest_rates_list = []
while True:
investment = input("Please enter the amount to be invested ")
periods = input("Please enter the number of periods for investment maturity ")
if int(periods) < 0:
break
interest_rates = input("Please enter the interest rate for each period ")
interest_rates_list.append(interest_rates)
If you input is something like:
4 5 12 8 42
then you can simply split it up by space and assign to values
list:
values = input().split()
If your input something like 4,5,12
, then you need to use split(',')
.
You can split
the input string
into several string
and then convert it to float
. This can be done in one line.
interest_rates = list(map(float, interest_rates.split(",")))
Here I go a step further, your next move will be to calculate some return based on interest rates, and so you will need float/integer to do so.
The python string function split can accept a delimiter character and split the input string into a list of values delimited by that character.
interest_rates = input("Please enter the interest rate for each period ")
interest_rates_list = interest_rates.split(",")
If you take the input, you can convert it to a string by using:
str(interest_rates)
Let this be variable A So, A = str(interest_rates)
Now, to seperate each entry of the interest rates, we do:
interest_rates_list = A.split(' ')
This function literally splits the string at all spaces and returns a list of all the broken pieces.
NOTE: if you do A.split(*any string or character*)
it'll split at the mentioned character. Could be ',' or ';' or ':', etc.
Now you can iter over the newly formed list and convert all the numbers stored as string to ints or floats by doing
for i in interest _rates_list:
i = float(i) #or int(i) based on your requirement
