Question

Please create a program to simulate Random Access Memory using PYTHON language:

1. Create an array at least 12K long
2. Set up a word length (8 bits)
   
3. Fill the Array with Random Data. (8bits each)
   
4. Read and Return(display) the data from the 100th record
5. Read and Return(display) the data from the 1000th record
6. overwrite the 99th record and the 999th record with zero’s

Again

7. Read and Return(display) the data from the 100th record
8. Read and Return(display) the data from the 1000th record

1. How many records can your array hold?

10. Do a dump(display) of every other record!

Answer 1

import random
import sys
array=[]*12000

bitList = []
for j in range(12000):
    bitList = []
    for i in range(0, 8):
        x = str(random.randint(0, 1))
        bitList.append(x)
  
    bitstring= ''.join(bitList)
    array.append(bitstring)

#read and display 100th record
_100th = array[99]
print(_100th)
#read and display 1000th record
_1000th = array[999]
print(_1000th)
#overwrite 99th and 999th record
array[98]='00000000'
array[998]='00000000'
#read and display 100th record
_100th = array[99]
print(_100th)
#read and display 1000th record
_1000th = array[999]
print(_1000th)
#maximum size of array is platform dependent, it is dependent on RAM

print("Your array can hold max records: ",sys.maxsize)
#printing alternate elements
i=0
while(i<len(array)):
    print(array[i],end=" ")
    i = i+2
