This is my code:
import math
def get_numbers():
print("This program will compute the mean and standard deviation")
file1 = input("Please enter the first filename: ")
file2 = input("Please enter the second filename: ")
x = open(file1, "r")
y = open(file2, "r")
nums = x.readlines()
nums2 = y.readlines()
return nums, nums2
def to_ints(strings):
num_copy = []
for num in nums:
num_copy.append(float(num))
return num_copy
return to_ints(nums), to_ints(nums2)
def mean(nums):
_sum = 0
return(sum(nums)/len(nums))
def main():
data = get_numbers()
m = mean(data[0])
m2 = mean(data[1])
print("The mean of the first file is: ", m)
print("The mean of the second file is: ", m2)
main()
This is the output of my updated code:
Traceback (most recent call last):
File "/Applications/Python 3.7/exercises .py", line 37, in
main()
File "/Applications/Python 3.7/exercises .py", line 33, in main
m = mean(data[0])
File "/Applications/Python 3.7/exercises .py", line 29, in mean
return(sum(nums)/len(nums))
TypeError: unsupported operand type(s) for +: 'int' and 'str'
