Python view Byte Code for the given script

Python view Byte Code for the given script


Normal execution syntax
python file_name.py

For retrieving the Byte Code information the execution syntax is,
python -m dist file_name.py

which will display in a disassembler format (human readable format)

Example :

# simple.py

a=10

b=20

c=a+b
print(c)

#output 

30

#cat bytecode.py

a=10
b=20
c=a+b
print(c)

#python3.6 bytecode.py

30

#python3.6 -m dis bytecode.py
