Need Help Dealing with inputs
Question:
Begginer Question, So i have this problem where i receive a lot of inputs in different lines like:
Inputs:
1
2
0
2
1
And i want to sum them or store them in any kind of list to Sum them latter, how can i do this?
I mean, i could store a variable for each one of them like:
a1 = int(input())
a2 = int(input())
ax = int(input())
....
and then
result = a1+a2+ax...
print(result)
but that’s not pratical. Someone can explain me on how to store and sum them in a list?
i think that i could do something like this too
x = int(input())
and use
x += x
Answers:
Just use python lists:
inputlist = []
for i in range(5):
inputlist.append(int(input))
result = sum(inputlist)
Note, I just put a 5 there to ask for 5 values. Ask however many inputs you want.
you could use a while loop, or a for loop for it. If you are provided the number of inputs in advance in a variable x
, you can start with a for loop.
x = int(input("Number of Inputs> ")) # If you know the certain number of inputs
# that you are going to take, you can directly replace them here.
answer = 0
for i in range(x):
answer += int(input())
print("Answer is", answer)
If you do not know the amount of inputs in advance, you can implement a while loop that will take input until a non-integer input is given.
answer = 0
while True:
x = input()
try:
x = int(x) # Tries to convert the input to int
except ValueError: # If an error occurs, ie, the input is not an integer.
break # Breaks the loop and prints the answer
# If all goes fine
answer += x
print("Answer is", answer)
And obviously, we also have a classic alternate to all this, which is to use python list
, these can store numbers and we can process them later when printing the answer. Although, I would have to say if the number of input is large, then the most efficient manner is to use either of the above solution due to their memory footprint.
x = int(input("Number of Inputs> ")) # If you know the certain number of inputs
# that you are going to take, you can directly replace them here.
inputs = []
for i in range(x):
inputs.append(int(input()))
print("Answer is", sum(inputs))
I’m also a beginner, but here’s a solution I came up with:
new_list = []
for entry in range(10):
new_list.append(int(input()))
print(sum(new_list))
