#For Loop Example - 1:

my_Money5 = ["Dollar","Rupee","Ruble"]

for Money in my_Money5:

      print (Money, "Currency")

      

#For Loop Example - 2:

for i in range(1000):

    print ("i= ", i)

    if (i == 999):

        break

#While Loop:

count = 0

while count < 10:

Python Class 109 - Kapil Sharma

1. while loop: Works till the time condition meet.

2. for loop: works for number of iterations.

3. function: Pre-fabricated code. 

    "def xyz(x): "

4. Class: It's a template of one or multi-functions features and variables.

    Classes can be inherit from super-class to child-class.

    First make class than make its objects to use it's resources.

5. Constructor: Special method in a class. As soon user create object.

    It executed it self, no need to call it.

6. Import: User can import python modules, by using import cmd.

    import xyz > xyz.abc()

    Also, any edit in the import module source file, user needs to,

    reload(xyz) cmd to update the import module in the source code.

7. dir(math) > help(math): This is the way to show help in details.

Python Class 108 - Kapil Sharma

Cheet Sheet: 

1. List = Arrays.
   List = ["One","Two","Three"];
   print List[2];

2. Tuple() = List, but its cannot be changed. (Unmutable)/xyz[2]

3. Sets = Are similar to list, un-ordered collection of unqiue elements.
   No, duplicates.

4. Dictionaries{} = Arrays. Un-order collections of key value pairs.
   dict = {"Key":"Value"}

5. __XYZ = Is declaring local variable by adding "__"

6. pop / remove: Both do the same thing.
   But implementation is different. In "pop" user needs
   to give index id: xyz.pop(1) / xyz.remove("abc")

7. xyz.find("abc"): Give the location index id of the text. 

8. "is": For same value, like one = two = [1,2,3] its true.

9. "in": For checking true values, "s" in "Kiwi" its false.
