| In Python 2, print is considered to be a statement and not a function. | In Python 3, print is considered to be a function and not a statement. |
| In Python 2, strings are stored as ASCII by default. | In Python 3, strings are stored as UNICODE by default. |
| On the division of two integers, we get an integral value in Python 2. For instance, 7/2 yields 3 in Python 2. | On the division of two integers, we get a floating-point value in Python 3. For instance, 7/2 yields 3.5 in Python 3. |
| In Python 2, exceptions are enclosed in notations. | In Python 3, exceptions are enclosed in parentheses. |
| The values of global variables do change in Python 2 if they are used inside a for-loop. | The value of variables never changes in Python 3. |
| In Python 2, the xrange() function has been defined for iterations. | In Python 3, the new Range() function was introduced to perform iterations. |
| Python 2 has more complicated syntax than Python 3. | Python 3 has an easier syntax compared to Python 2. |
| A lot of libraries of Python 2 are not forward compatible. | A lot of libraries are created in Python 3 to be strictly used with Python 3. |
| Python 2 is no longer in use since 2020. | Python 3 is more popular than Python 2 and is still in use in today’s times. |
| Python 2 codes can be ported to Python 3 with a lot of effort. | Python 3 is not backward compatible with Python 2. |
| Python 2 was mostly used to become a DevOps Engineer. It is no longer in use after 2020. | Python 3 is used in a lot of fields like Software Engineering, Data Science, etc. |
