Question

I am new to Python and want to read keyboard input into an array. The python doc does not describe arrays well. Also I think I have some hiccups with the for loop in Python.

I am giving the C code snippet which I want in python:

C code:

int i;

printf("Enter how many elements you want: ");
scanf("%d", &n);

printf("Enter the numbers in the array: ");
for (i = 0; i < n; i++)
    scanf("%d", &arr[i]);

Answer 1

raw_input is your helper here. From documentation –

If the prompt argument is present, it is written to standard output
without a trailing newline. The function then reads a line from input,
converts it to a string (stripping a trailing newline), and returns
that. When EOF is read, EOFError is raised.

So your code will basically look like this.

num_array = list()
num = raw_input("Enter how many elements you want:")
print 'Enter numbers in array: '
for i in range(int(num)):
    n = raw_input("num :")
    num_array.append(int(n))
print 'ARRAY: ',num_array

P.S: I have typed all this free hand. Syntax might be wrong but the methodology is correct. Also one thing to note is that, raw_input does not do any type checking, so you need to be careful…
