In python can list be created in runtime. If yes means please explain me the code. Thanking u <3

Question

In C, C++ one can create an array in runtime with size N using looping. Is that possible in python using list or which concept can be used to achieve it. :) Thanking u in advance 😊

Answer 1

That was an example how to create a list of numbers using input by space. Map is function that gives you instructions applying some function to each item. So map receives two parameters: some function and list of items. In that example input().split() gives you a list of elements separated by space. But those elements aren't numbers. And "int" in map converts all that elements to integers. Finally you have a list of numbers.

Answer 2

# That what you mean?
l = list()
for i in range(10):
l.append(i/2)
print(l)
# or this:
l = [i/2 for i in range(10)]
print(l)

Answer 3

l = [input("Gimme " + str(i) + ": ") for i in range(10)]

Answer 4

For example: list l of numbers from 0 to determined n:
n=int(input())
l=[i for i in range(n+1)]
Other way:
for i in range(n+1):
l.append(i)
You can use other methods to modify your list as you want.

Answer 5

In this case you can use map with list comprehension.
l=list(map(int, input().split()))
print(l)

Answer 6

In this case you can use map with list comprehension.
l=list(map(int, input().split()))
print(l)
Sir can you explain it more clearly .

Answer 7

Sir thanka a lot ☺. Now I got it. Time to play with it...

Answer 8

Thank you frnds but this loops assigns index values to list l, but I need to get input in runtime. So can u help me with it's solution. ☺

Answer 9

Frnds i have found solution in another logic :
N = int(input("Enter Size of Array:"))
l = list()
print("Enter The Elements:")
for i in range(N):
ip = int(input())
l.append(ip)
print("Elements in list:",l)
sum_number = 0
for i in range(N):
sum_number = int( l[i] ) +sum_number
print("Sum of Array",sum_number)
This program gets input from user and then sums all elements in the list .
Thank you guys :)
