In this guide, we will show you a short script that can be used to convert a binary number to a decimal number in Python on Linux. This script uses casting which is used to convert a variable from one type to another. In this case, we use Python casting to convert a string to decimal number that is an integer.
Check out the script below to use it on your own system.
In this tutorial you will learn:
- How to convert binary number to decimal with Python
| Category | Requirements, Conventions or Software Version Used |
|---|---|
| System | Any Linux distro |
| Software | Python |
| Other | Privileged access to your Linux system as root or via the sudo command. |
| Conventions |
# – requires given linux commands to be executed with root privileges either directly as a root user or by use of sudo command$ – requires given linux commands to be executed as a regular non-privileged user |
Python Script
When you attempt to use casting to convert a variable type to integer, make sure that your variable input type is a string.
Without further ado, here is the Python script. Copy and paste the section below into a new file on your computer.
#!/usr/bin/env python
while True:
try:
# Try to convert bunary to decimal
decimal_num = int(raw_input("Enter a binary number: "), 2)
# If we fail we ask again user to enter binary number
except ValueError:
print "Your input is not a binary number! Please try again."
else:
# Exit program if the conversion from binary to decimal was successful
break
# print converted decimal number
print decimal_numSave your script, for example with name binary2decimal.py, then make it executable and run the script:
$ chmod +x binary2decimal.py $ ./binary2decimal.py
That’s all there is to it. Now you will have an easy time converting binary numbers to decimal integers with Python.
