Variable

Variable refers to a value of a change

Variables can only consist of letters, numbers, underscores, and cannot start with a number

Python keyword cannot be variable

Name ==print(name,age)

Conditional statements

If Else

Name = input ("name:")if name = = Amada    :Print( " Hello Amand " )else:    pass

While loop

Count = 0 while Count <:       print      (count)= Count + 1

Homework

1. Use while loop input 1 2 3 4 5 6 8 9 10

Count = 1 while count < one:   if  count = =7       :pass    else:       Print(count)   = count + 1

2. For all numbers of 1-100

s == 0 while Count <101:    = s + count    = count + 1    Print(count)    print(s)

3. All odd numbers in output 1-100

Count = 1 while count < 101:     = count% 2     if a = = 1         :print  ( count)     = Count +1

4. All even numbers in output 1-100

Count = 1 while count < 101:     = count% 2     if a = = 0         :pri NT  (count)     = Count +1

5, Beg 1-2+3-4+5 ... 99 of all numbers of the and

s == 0 while C <100:    = c% 2    if q = = 0        := S- c
    Else:        = s + c    = c +1print(s)

6. User Login (three chance retry)

Count =0 whileCount < 3: Name= Input ("Account Number:") passwd= Input ("Password:")    ifName = ="Ada"  andpasswd = ="123":         Print("Welcome to login")          Break    Else:         Print("incorrect account or password") Count= Count + 1
