name = input("Enter name ")
age = input("Enter age")

print(name, " is ", age, " years old ")
-----------------------------------

# if

a = 10
b = 25
if a>b:
  print(a , " is big")
else:
   print(b , " is big ")
-----------------------------
# nested if
a = 10
b = 20
c = 17
big = 0
if a>b:
  if a>c:
    big=a
  else:
    big=c
elif b>c:
  big=b
else:
  big=c
print("Biggest is ", big)
----------------------------------

# if and loop combination:

lst = [10,20,34,23,12,34,23,45]

big = lst[0]

for v in lst:
  if v>big:
     big=v
print("max of the list ", big)

-------------------------

for v in lst:
   tot += v
   cnt += 1
avg = tot/cnt
print("avgerage : ", avg)
-------------------------

Accessing List Elements:



------------------------------

updating List Elements:


lst[3] = 100
print(lst)
lst[4:7] = [250]*3
print(lst)

a = [1]*10
print(a)
--------------------------

adding elements to list:

lst = [10,20,34,23,12]

lst.append(100)
lst.append(200)
print(lst)

-----------------------------

merging lists:

lst = [10,20,34,23,12]

lst2 = [100,200,300,400,500]

l = lst + lst2

lst += lst2
print(l)
print(lst)

---------------------------

Transformations:

names = ["ravi", "rani", "vani", "venu", "siri"]

names2 = []

for x in names:
    names2.append(x.upper())
print(names2)
------------------------------

Transformations:
  first char in to upper case,
  and all remainings into lower case.

names = ["ravi", "rani", "vani", "venu", "siri"]

names2 = []

for x in names:
     fc = x[0].upper()
     rc = x[1:].lower()
     name=fc+rc
     names2.append(name)
print(names2)
