如何找到中位数？

Question

I am trying to create a function that can get any number of inputs and find the median. I feel like I am going about this all wrong, I cannot get this functional.
What do I need to do?

1. I made my list
2. I asked user for inputs
3. I sorted with numpy
4. I printed median

Code:

import numpy

numbers = [1,2,3]                
1 = input("Please type your first number")            
2 = input("please type your second number")       
3 = input("please type your third number")       
median = numpy.median(numbers)            
print(median) 

What I am trying to accomplish:

What numbers would you like to find the median for? 1,2,3,4,5,6,7
The median is: 4

Answer 1

You should store the numbers in a list, and use a loop to add numbers to it.

import numpy

size = int(input("Enter number of numbers you would like to enter"))
numbers = []
for i in range(size):
    numbers.append(int(input("Please type in number %d" % i)))

median = numpy.median(numbers)  

print(median) 

Your approach fails because you try to use numbers as variable names, which is not valid.

Answer 2

You cannot assign values to 1, 2, or 3. Additionally, you need to convert the strings from input to int s. Try some simple changes.

import numpy                
input1 = input("Please type your first number")            
input2 = input("Please type your second number")       
input3 = input("Please type your third number")
numbers = map(int, [input1, input2, input3])
median = numpy.median(numbers)            
print(median)
