Comments & if else in Python Script

user@ngelinux$ cat third.py 
#!/usr/bin/python

### This is a comment
### In python comments start from hash sign
print('Verify if you are eligible for voting...')
age=int(input('Please enter your age'))

### condition always start with intended block in python
### We use colon in if else statement in python
if (age>18):
	print('You are eligible to vote')
else:
	print('You are not eligible to vote');

 

Execution of the script

user@ngelinux$ ./third.py

Please enter your age4
You are not eligible to vote

user@ngelinux$ ./third.py 
Verify if you are eligible for voting...
