+# Variables
+## Variables helps us to store key&value information that we would like to refer to its value throughout the program
+```python 
+name = "Michael"
+age = 30
+
+print(name, "is my name")
+print(name, "is", age, "years old")
+print(name, "likes to eat pizza")
+print("This man's name is", name)
+
+
+
+```
+## Exercise:
+
+### Is there a way that you can create more than one variable in one line of code ? Worth to search on web if this could be done!
+
+### Answer:
+```python
+a, b, c = 1,2,3 # a will receive 1, b will receive 2, c will receive 3
+#More examples:
+print(a)
+print(b)
+print(c)
+
+name, age = "Jim", 25
+print(name)
+print(age)
+```

+# Types and Conversions
+## We can divide in any programming language some variable types into categories
+```python 
+#All types:
+name = "John" #Strings - Characters that we want to create/store variables
+age = 30 #Integers - Numbers without decimal point
+temperature = 90.5 #Floating Numbers / Floats  - Numbers with decimal point
+is_raining = False #Booleans - Describes a situation - True or False
+
+#str() - Will convert to string
+#int() - Will convert to integers
+#float() - Will convert to floating numbers
+#bool() - Will convert to booleans
+
+#Temperature average program:
+temperature1 = 95.5
+temperature2 = 94.5
+average = (temperature1 + temperature2) / 2
+print(int(average))

+#We always want to assign the input built-in function to a variable

+
+###  Write a program that will receive three inputs, grade_one, grade_two, grade_three. Try to write a program that will print the average of the received three grades.
+
+### Answer:
+```python
+#We need to force each input to be integers (float would also work)
+grade_one = int(input("What is the first grade?"))

+#Not all the methods out there, will affect the value of the variable that you apply the method on.
