Question

Octal numbers have a base of eight and the digits 0–7. Write the scripts octalToDecimal.py and decimalToOctal.py, which convert numbers between the octal and decimal representations of integers. These scripts use algorithms that are similar to those of the binaryToDecimal and decimalToBinary scripts developed in the Section: Strings and Number Systems.

Answer 1

See explaination

Step-by-step explanation:

#input

o_t_n=int(input('Enter a string of octal digits: '))

#required variables

i = 1

dc = 0

#loop for conversion

while (o_t_n != 0):

#to find remainder

rmd = o_t_n % 10

o_t_n //= 10

dc += rmd * i

i *= 8

#print the results

print('The integer value is ',dc)

# decimalToOctal.py

#input

d_c_n=int(input('Enter a decimal integer: '))

print("Quotient Remainder Octal")

#required variables

i = 1

o_c_n = 0

num=""

#loop for conversion

while (d_c_n != 0):

#to find remainder

rm = d_c_n % 8

d_c_n //= 8

o_c_n = o_c_n + rm * i

i *= 10

num = str(rm)+num

print("%5d%8d%12s" % (d_c_n, rm, num))

#print the results

print('The octal representation is ',o_c_n)
