Function

### FUNCTION =======>>>>>>>
# we use def<----   for function making
# EXAMPLE 1-->>
# def add(a,b):
#     a = int(input("Data 1 = "))
#     b = int(input("Data 2 = "))
#     c = a+b
#     return c
#
# c = add("data1","data2")
# print(c)

#EXAMPLE 2-->>

# def print_name():
    # name = input("Enter Name = ")
    # print(name.upper())

# print_name()

# in this example we know these new things--->>>

# {.upper()}--->>> this function gives the uppercase letters of given value


# EXAMPLE 3------>>>>>>
#
# def marks_sum(a,b,c):
#     sum = a+b+c
#
#     return sum
#
# def marks_avg(sum):
#     avg = sum/3
#
#     return avg
#
# def marks_grade(avg):
#     if avg>80:
#         print("Grade A")
#     elif avg>60:
#         print("Grade B")
#     elif avg>40:
#         print("Grade C")
#     else:
#         print("FAIL")
#
#
# sum = marks_sum(int(input("English = ")),int(input("Hindi = ")),int(input("Maths = ")))
# avg = marks_avg(sum)
# print("Total Marks : {} Average : {}".format(sum,avg))
# marks_grade(avg)
#
#
# # here we learn about a new FUNCTION WHICH IS CALLED AS PLACEHOLDER(symbol =-> {})
# it is used inside the print function and inside the aphostrophe
# to impliment this we use  at the end of apostrophe -->> .format(var1,var2)
#
# example-->>
# print("Name : {} Age : {} Sex : {}".format(var1,var2,var3))

#   global   -->>>>this statement is used to have the global variable in the function

 #example 1--->

# glob_var = 154
#
# def var():
#      global glob_var
#      global_var = 156
#      print(global_var)
#
# var()


#   SOME INBUILT FUNCTIONS ====>>>>

# (1): sum  --->> it will give the sum of all the tuple
#
# x = [10,34,12,56]
# print(sum(x))

# (2): min  ---->>> it will give th mnimum value of the tuple

# x = [10,34,12,56]
# print(min(x))

# (3): max  ---->>> it will give the maximum of the tuple
# x = [10,34,12,56]
# print(max(x))

#(4): .index ----->>>>  if we put a substring of a string it will give the index number of starting string..
#
# str = "Hello There I am Using Whatsapp"
#
# print(str.index("Whatsapp"))

#(5): YOU CAN ADD UP LIMITS IN THIS .index Function

# str.index("Whatsapp",10,len(stm))
# in first column the substring .....in second column the initial value ....in third column the final value at which you have to search the

# (6) : help() function gives you the help how to run the inbuilt functions and the required parameters


# FUNCTION DOCUMENTATIOIN---->>>
# Whenever we built a functiion we need a documentation to recognize the function clearly for this in
    # user built function we use triple quotes(""")   with this you can classify the detailss of the function
    # example------>>>>>>

# def add(a,b):
#     """
#     In this Function We Add  Two Parameters a & b
#     :param a: A int datatype variable
#     :param b: A int Datatype variable
#     :return: Sum Of Both
#     """
#
#     c = a+b
#     return c

# help(add)

# WE CAN ALSO USE THIS FUNCTION INSTEAD OF help() to view the documentation
# [.__doc__]<<<--

# ---------------------------------------------------------------------------------------

# DEFAULT ARGUEMENTS------>>>>>>

# If you USE ANY USER BUILT FUNCTIONS AND IF NOT GIVE ANY PARAMETERS IT WILL USE DEFAULT PARAMETERS
# {!!!!WARNINGGGGGGG !!!! ----  ONLY GIVE PARAMETERS IN FUNCTION FROM RIGHT TO LEFT!!!}
# EXAMPLE---->>

# def netflix(name, genere = "Thriller" , duration = "2 Hours"):
#     print("SERIES : {}\nGENERE : {}\nDURATION : {}\n".format(name,genere,duration))
#
#
# netflix("Peaky Blinders",duration = "8 Hours")
# netflix("Money Heist",genere = "Myestry",duration = "8 hours")
# netflix("The Space Between Us")

# ARBITARY ARGUEMETS ---->>>>

# THE ARBITARY ARGUEMENTS DEFINED IN FUNCTION WITH  (*args)
# THIS WILL TAKE VARIABLES AS A TUPLE  AND we HAVE TO USE FUNCTIONS GTO ADD AND MINUS LIKE
# sum()
# EXAMPLE------>>>>>>

# def aarg(*args):
#     c = sum(args)
#     print(c)
#     return c
#
# aarg(1,2,3,4,5,6,7,8,9,10)

# LAMBDA FUNCTION---->>>>>
# It is a function which is used in place of def to make function it is more easy than the function to write over an impliment
# Example ----->>>>>>>>
# employee_salary = [4120,12414,1882,34981,8483]
# var = list(filter(lambda s:s>5000,employee_salary))
# print(var)

# filter()  <---- this function used to filter the inputs in your own way
