What are Strings? The following example shows a string contained within 2 quotation marks: # Use quotation marks for defining string "Michael Jackson" We can also use single quotation marks: # Use single quotation marks for defining string 'Michael Jackson' A string can be a combination of spaces and digits: # Digitals and spaces in string '1 2 3 4 5 6 ' A string can also be a combination of special characters : # Special characters in string '@#2_#]&*^%$' We can print our string using the print statement: # Print the string print ( "hello!" )

Types of objects in Python Python is an object-oriented language. There are many different types of objects in Python. Let's start with the most common object types:  strings ,  integers  and  floats . Anytime you write words (text) in Python, you're using  character strings  (strings for short). The most common numbers, on the other hand, are  integers  (e.g. -1, 0, 100) and  floats , which represent real numbers (e.g. 3.14, -42.0). # Integer 11 # Float 2.14 # String "Hello, Python 101! You can get Python to tell you the type of an expression by using the built-in  type()  function. You'll notice that Python refers to integers as  int , floats as  float , and character strings as  str . # Type of 12 type ( 12 ) # Type of 2.14 type ( 2.14 ) # Type of "Hello, Python 101!" type ( "Hello, Python 101!" )

Say "Hello" to the world in Python # Try your first Python output print('Hello, Python!') After executing the cell above, you should see that Python prints  Hello, Python! . Congratulations on running your first Python code! What version of Python are we using? There are two popular versions of the Python programming language i n use today: Python 2 and Python 3. The Python community has decided to move on from Python 2 to Python 3, and many popular libraries have announced that they will no longer support Python 2. Since Python 3 is the future, in this course we will be using it exclusively. How do we know that our notebook is executed by a Python 3 runtime? We can look in the top-right hand corner of this notebook and see "Python 3". We can also ask directly Python and obtain a detailed answer. Try executing the following code: import sys print ( sys . version ) 3.6.7 | packaged by conda-forge | (default, Nov 6 2019, 16:19:42) [GCC 7.3.0] Writing comment...
