PYTHON 3.0 HELP!! NOT JAVA

-Create a list consisting of the negative values in the list numbers. Associate the new list with the variable negatives.

-The factors of an integer are those numbers that evenly divide into the integer. Given the integer n, create a list of all the factors of n, excluding 1and n itself. The list should be ordered from smallest to largest. Associate the new list with the variable factors.

Explanation / Answer

NOTE:

Out of three questions provided, i did not clearly understand the first questoin. So has written two solutions for first part. If you have any questions or concerns please let me know.

Code-1:

#!/usr/local/bin/python3

# Create a list consisting of the negative values in the list numbers. Associate the new list with the variable negatives.

def main():

negatives = []

i = -1

# creating a list of 100 negative numbers

while i != -100:

negatives.append(i)

# incrementing negative numbers

i -= 1

print(negatives)

if __name__=='__main__':

main()

Execution and output:

Unix Terminal> python3 negatives.py

[-1, -2, -3, -4, -5, -6, -7, -8, -9, -10, -11, -12, -13, -14, -15, -16, -17, -18, -19, -20, -21, -22, -23, -24, -25, -26, -27, -28, -29, -30, -31, -32, -33, -34, -35, -36, -37, -38, -39, -40, -41, -42, -43, -44, -45, -46, -47, -48, -49, -50, -51, -52, -53, -54, -55, -56, -57, -58, -59, -60, -61, -62, -63, -64, -65, -66, -67, -68, -69, -70, -71, -72, -73, -74, -75, -76, -77, -78, -79, -80, -81, -82, -83, -84, -85, -86, -87, -88, -89, -90, -91, -92, -93, -94, -95, -96, -97, -98, -99]

Code-1:

#!/usr/local/bin/python3

# Create a list consisting of the negative values in the list numbers. Associate the new list with the variable negatives.

def main():

negatives = [-1, -10, -20, -30, -40, -50]

print(negatives)

if __name__=='__main__':

main()

Execution and output:

Unix Terminal> python3 negatives_1.py

Code-2:

#!/usr/local/bin/python3

# The factors of an integer are those numbers that evenly divide into the integer.

# Given the integer n, create a list of all the factors of n, excluding 1 and n itself.

# The list should be ordered from smallest to largest. Associate the new list with the variable factors.

def main():

# initializing an empty list factors

factors = []

# taking input from the user

n = int(input('Enter the integer n? '))

# iterating from numbers 2 to n-1

for i in range(2, n):

# checking if n is divisible by i. If it is then append to the factors list

if n % i == 0:

factors.append(i)

# sorting the numbers from smallest to largest

factors.sort()

print('Factors of the number excluding 1 and n are: ')

# printing the factors of number

for num in factors:

print(num, end=' ')

print(' ')

if __name__=='__main__':
