 Arguments

information can be passed into function as arguments

EXAMPLE:

the while loops , break statement,continue statement

 the while loops :

with the while loops we can execute a set of statement as long as condidtion is true 

example:

a = 1

while a < 10:

  print(a)

  a = a+1

output:

the break statement:

i = 1

while i < 6:

  print(i)

  if i == 3:

    break

  i += 1

output:

the continue statement:

i = 0

while i < 6:

  i += 1

  if i == 3:

    continue

  print(i)

syntax:

lambda arguments: expression

example:

x = lambda a:a+50

print(x(12))

x = lambda a ,b: a*b

print(x(20,2))

x = lambda a,b,c,d : a-b*c+d

print(x(20,2,2,15))

Main Key Points

• input() // for get userinput value
• int()    // 
• eval() //
• float()  //

 x=input("enter your age -")

print(x)

y=int(input("enter your age -"))

print(y)

z=float(input("enter your age-"))

print(z)

s=eval(input("ente your age-"))

print(s)

output:

Check user is eligible for voting in python

 

print("Check user is eligible for voting")

x = int(input("enter your age - "))

if x < 18:

  print(" sorry you'r under 18 ")
