Binary Converters Assignment

Objectives

• You will write Python programs to convert the following:
  • Binary <-> Decimal
  • Binary <-> Hexadecimal

Directions

1. Create a Python program named binaryConverters.py
2. Create the following 4 functions:
   1. bin2dec(bStr)
      • This function takes a string bStr as a parameter, and the string contains 1s and 0s that represent a binary number
      • Return the decimal number (int) of the binary string
   2. dec2bin(dNum)
      • This function takes a number dNum as a parameter, which is an integer
      • Return the binary string that corresponds to the integer
   3. bin2hex(bStr)
      • This function takes a string bStr as a parameter, and the string contains 1s and 0s that represent a binary number
      • Return the hexadecimal string that represents the binary string
   4. hex2bin(hexStr)
      • This function takes a string hexStr as a parameter, and the string contains hexadecimal (0-9, a-f, A-F)
      • Return the binary string that represents the hexadecimal

Testing

1. Test out each of your functions on your own
2. Mr. Bui will give you his test cases next week
