int(3) and int('3') is there a difference? (python3.5)

[freemedia2018]

Python is one of my favourite languages.

I think they only mentioned int('2') to demonstrate that int() can convert string data to integer data.

So its a string that can be added, multiplied, divided etc?

No, a string is more like a list of characters. If you multiply a string by a number, you get a string:

Code:

print("l" + "ol" * 5)

An integer is a numeric value that rounds to the nearest whole number. If you multiply an integer by another numeric value, you get a numeric value.

Code:

print(2.7 * 5)

type is a great command in Python. Here are some things you can try:

Code:

>>> type('5')

>>> type(5.0)

>>> type(int(5))

>>> type(int('5'))

>>> type(str(5))

>>> int('5.0')

>>> float('5.0')

>>> type(float('5.0'))

>>> int(float('5.0'))
