Python lists and sorting randomly generated numbers

I have this

import random 

a = random.randint(1,100) 
b = random.randint(1,100) 
c = random.randint(1,100) 
d = random.randint(1,100) 
e = random.randint(1,100) 

print "The numbers are a:",a,"b:",b,"c:",c,"d:",d,"and e:",e 
print "The numbers in ascending order:" 
list1=[a,b,c,d,e]
list1.sort(key=int)
print a
print b
print c
print d
print e`

But I can't get it to understand that I want to print the new values and not the old ones for a-e

By creating and sorting list1 you change the contents of the list, not the actual variables a, b, c, d and e. If you wanted python to print the "new values", you would have to print list1.

import random 

a = random.randint(1,100) 
b = random.randint(1,100) 
c = random.randint(1,100) 
d = random.randint(1,100) 
e = random.randint(1,100) 

print "The numbers are a:",a,"b:",b,"c:",c,"d:",d,"and e:",e 
print "The numbers in ascending order:" 
list1=[a,b,c,d,e]
list1.sort(key=int)

for num in list1:
    print num

import random 

a = random.randint(1,100) 
b = random.randint(1,100) 
c = random.randint(1,100) 
d = random.randint(1,100) 
e = random.randint(1,100) 

print "The numbers are a:",a,"b:",b,"c:",c,"d:",d,"and e:",e 
print "The numbers in ascending order:" 
list1=[a,b,c,d,e]
list1.sort(key=int)
for item in list1:
    print(str(item) + '\n')

Something wrong with your conception. Yeah, a,b,c,d,e are created by random.randint(). When you sort the list1, a,b,c,d,e won't be changed by the changes of list1. Because in list1, only values copied from a,b,c,d,e inside, not a,b,c,d,e themselves. So you cannot change the values of a,b,c,d,e by changing the list1.

This works

import random 

a = random.randint(1,100) 
b = random.randint(1,100) 
c = random.randint(1,100) 
d = random.randint(1,100) 
e = random.randint(1,100) 

print "The numbers are a:",a,"b:",b,"c:",c,"d:",d,"and e:",e 
print "The numbers in ascending order:" 
list1=[a,b,c,d,e]
list1.sort(key=int)

for item in list1:
    print item

When you sort the list, the original variables that you assigned do not get changed, only the contents of the list do.

You can reassign the variables from the sorted list:

list1=[a,b,c,d,e]
list1.sort(key=int)
a, b, c, d, e = list1

print a
print b
print c
print d
print e

You put the numbers of the variables into the list list1. If you sort the list you don't change the values of a to e.

If you want to print them sorted itterate over the list and print all the elements, then they are sorted.

for current in list1:
    print current

Iterate through list1 and just print each value:

for number in list1:
    print number
