1. if statement¶

In [2]:

x = 20
y = 23

if x == y:
  print("x equals y")
elif x < y:
  print("x is less than y")
else:
  print("x is greater than y")

x is less than y

2. while statement¶

In [3]:

i = 1
x = 2
# print the mathematical power of x raise to i 
while i <= 10:
  print(x, "^", i, " = ",  x**i)
  i += 1

2 ^ 1  =  2
2 ^ 2  =  4
2 ^ 3  =  8
2 ^ 4  =  16
2 ^ 5  =  32
2 ^ 6  =  64
2 ^ 7  =  128
2 ^ 8  =  256
2 ^ 9  =  512
2 ^ 10  =  1024

In [4]:

arr = [3, 7, 8, 8, 9, 1]

for i in arr:
  print(i)

In [5]:

for i in range(1, 10):
  print(i)

In [6]:

for i in range(1, 10, 2):
  print(i)

In [7]:

arr = [3, 6, 10, 334, -5, 33, 48, -11, 20]

for i in arr:
  if i < 0:
    print("First n-ve number : ", i)
    break

First n-ve number :  -5

In [8]:

for i in arr:
  if i < 0:
    continue
  print(i)
