Question 1:

a = 0while a < 10:    a +=1        if a == 7:        continue    print(a)

Question 2:

Method 1:

a = 0b = 1while b <= 100:    a = a + b    b += 1print(a)

Method 2:

a = 0for i in range(101):        a = a + i        print(a)

Question 3:

a = 0while a <= 100:    a += 1    if(a%2) == 0:        print(a)

Question 4:

Method 1:

a = 0while a <= 100:    a += 1    if(a%2) == 0:        print(a-2+1)

Method 2:

a = 0while a <= 99:    a += 1    if(a%2) != 0:        print(a)

Question 5:

a = 0b = 0while a < 99:   a += 1   if a%2 == 1:      b += a   else:      b -= aprint(b)

Question 6:

A = 0 while a <3: name = input ("Enter the User name:") password = input ("enter the password :") a + = 1 if name = 'wxd 'and password = '000000': print ("Login successful") exit () else: print ("input error, enter ") print (" three input errors, exit ") again ")
