Trying to do some some questions in a book yet I'm stuck with my arrays. I get this error:
count[i] = x
TypeError: 'int' object does not support item assignment
My code:
import pylab
count = 0
for i in range (0,6):
x = 180
while x < 300:
count[i] = x
x = x + 20
print count
Basically I need to use a loop to store values which increase until they hit 300 in an array. I'm not sure why I'm getting that error.
I might have worded this poorly. I need to use a loop to make 6 values, from 200, 220, 240... to 300, and store them in an array.
count
is an integer. Integers don't have indexes, only lists or tuples (or objects based on them) do.
You want to use a list, and then append values to it:
count = []
for i in range (0,6):
x = 180
while x < 300:
count.append(x)
x = x + 20
print count
You have defined count
as an int
number and as the error says ( 'int' object does not support item assignment
) you need a list instead , :
count = []
and use append()
function to append the numbers to your list :
for i in range (0,6):
x = 180
while x < 300:
count.append(x)
x = x + 20
print count
You don't need the while loop, you can use range with a start,stop,step:
count = []
for i in xrange (6):
for x in xrange(180,300,20):
count.append(x)
print count
Or use range with extend:
count = []
for i in xrange(6):
count.extend(range(180,300,20))
Or simply:
count range(180,300,20) * 6 `
Use dictionary
count = {}
for i in range (0,6):
x = 180
while x < 300:
count[i] = x
x = x + 20
print count
