In how many different ways, can you work in Python?
We can work in Python in two ways:
What are advantages/disadvantages of working in Interactive mode in Python?
Interactive mode is useful for testing code. We can type the commands one by one and get the result of error immediately for each command. Disadvantages of Interactive mode are that it does not save commands in form of a program and also output is sandwiched between commands.
What are the advantages/disadvantages of working in script mode in Python?
Script mode is useful for creating programs and then run the programs later and get the complete output. It is not suitable for testing code.
Write instructions to get the following result :
Math is Fun so don't be resistant
Just learn the rules, the rules are consistent
And most important, you must be persistent !
Adding fractions, get common denominators.
Multiply by missing factors to get the denominators.
Add numerators only, NOT denominators.
Do it in both interactive mode and script mode.
>>> print("Math is Fun so don't be resistant")
Math is Fun so don't be resistant
>>> print("Just learn the rules, the rules are consistent")
Just learn the rules, the rules are consistent
>>> print("And most important, you must be persistent !")
And most important, you must be persistent !
>>> print("")
>>> print("Adding fractions, get common denominators.")
Adding fractions, get common denominators.
>>> print("Multiply by missing factors to get the denominators.")
Multiply by missing factors to get the denominators.
>>> print("Add numerators only, NOT denominators.")
Add numerators only, NOT denominators.
