if age >=14:

    print ("your are eligible to play")

winning_number = 27

user_input = input("guess a number b/w 1 and 100: ")

user_input = int(user_input)

if user_input == winning_number:

    print("you win!!")

else:

    if user_input < winning_number:

        print("to low")

    else:

        print("to high")

print(user_input)

 

and or statement

Tips to remember while using python• if value is greater than age input age>=10, • position specified in list format user[0]==('a') or user[0]==('A')):)

user = input("what is your name: ")

age = input("what is your age: ")

age = int(age)

 

if age>=10 and (user[0]==('a'or user[0]==('A')):

else:

    print("you cannot watch movie")

 

if             elif         else       statements

Tips to remember while using python• if input value is equal to 0 & input value is less than 0  age==0 & a<0 ,

for multiple statements

age = input("what is your age: ")

name = "chirag"

 

if 'a' in name:

    print("a is present")

else:

    print("not present")

empty or not

Tips to remember while using python• strange example but very effective while user could input any thing or even can just hit a enter)

 

name = "chirag"

if name:

    print("empty string")

else:

    print("not empty")

name = input("enter your name: ")

 

if name:

    print(f"your name is {name}")

else:

    print("you din\'t any thing")

 

and        -              both statement should be true than only it could be true

Tips to remember while using python• checking 2 conditions are correct or not)

name = "abc"

age = 24

if name=="abc" and age==24:

    print("condition true")

else:

    print("condition false")

 

or            -              -              any 1 statement than it can be true

Tips to remember while using python• checking any 1 conditions is correct or not)

 

name = "abc"

age = 24

 

if name=="abc" or age==16:

    print("condition true")

else:

    print("condition false")

 

WHILE LOOP     

Tips to remember while using python

• it is printing every time hello world till the value doesn’t reach the while loop value (I is smaller equal to 10

• how while loop works  we assigned i+1 = 2 afterwards it adds +1 till the value 3,4,5,6, 10 comes  afterwards it stops)

i = 1

while i<=10:

    print("hello world")

    i = i+1

hello world

hello world

hello world

hello world

hello world

hello world

hello world

hello world

hello world

hello world

 

Tips to remember while using python

• Secret tip Using shortcut always remember, (f"hello world {i}")), in this we are getting the input value also to be printed as we are assigning i+1 value each time till it reaches 10

i = 1

while i<=10:

    print(f"hello world {i}")

    i = i+1

hello world 1

hello world 2

hello world 3

hello world 4

hello world 5

hello world 6

hello world 7

hello world 8

hello world 9

hello world 10

 

WHILE LOOP HOW TO SUM

Tips to remember while using python

Trick : we are getting a sum of 2 numbers till we reach at a value 10

It check what values are assigned and as per seeing we see while loop reverses the formula from bottom to the word while writte, but always what we need the output needs to be remembered

 

total=0

i = 1

while i<=10:

    total +=i

    i +=1

print (total)

55
