基礎練習問題

1.whileループを使用して1234568910を入力

a = 1
while a <= 10:
   if a == 7:
       pass
   else:
       print(a)
   a = a + 1

2.出力1-100以内の奇数

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

3.出力1-100以内の偶数

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

4.出力1-100すべての数値加算の合計

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

5.出力1-2+3-4+5.....99の和

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

 6.ユーザー登録、3回の再試行

count = 0
while count < 3 :
    user = input('      >>>:')
    pwd = input('     >>>:')
    if user == 'zjh' and pwd == '123456':
        print('    ')
        print('........')
    else:
        print('        ')
    count = count + 1
