Python is very progressive programming language. It's widely used in many areas.

In this blog post of "Python tutorials" I post some basic examples that will help you to get some basic knowledge and understand Python syntax. These examples are for Python 2.7 version.

Simple use of print command

>>> 'it\'s good to forgive'

"it's good to forgive"

Print sentence surrounded by '

>>> print '\'I am wealthy\''

>>> 'wealth' .startswith('w')

True

>>> 'wealth' .startswith('n')

False

>>> 'wealth' .startswith('weal')

True

Check if a word ends with certain alphabet/s

>>> 'wealth' .endswith('h')

True

False

>>> 'eal' in 'wealth'

True

>>> 'l' in 'health'

True

Check how many time some alphabet/s are in a sentence or words

>>> 'wealth health forgive good love humble smart'.count('h')

4

1

Convert lower alphabets to upper

>>> 'wealth'.upper()

'WEALTH'

Convert upper alphabets to lower

>>> 'WEALTH'.lower()

'wealth'

Capitalize first alphabet in a word

>>> 'wealth'.capitalize()

'Wealth'

>>> 'wealth health good'.title()

'Wealth Health Good'

Replace alphabet/s or word/s with others
