Python萌新自學日記1

補上第二章感覺自己會忘的筆記

對於字串大小寫的修改

.title()

使用製表符或換行符來新增空白

\t \n

第三章3-4

#3-4

list_name = ['dad', 'mum', 'sister']
print('dear '.title() + list_name[0].title() + ' thank for your coming')
print('dear '.title() + list_name[1].title() + ' thank for your coming')

print('dear '.title() + list_name[1].title() + ' thank for your coming')
print('dear '.title() + list_name[2].title() + ' thank for your coming')
#3-6

其實上面這串**還不是第三章的全部，還有後面乙個練習，但是由於時間關係（懶），後乙個練習明天再更新，今天這乙個練習裡的**打了我快乙個小時，原因是發現各種各樣的問題，比如pop彈出元素發現彈錯了，只能一行一行print去檢驗；del刪錯了，也只能一行一行的print檢驗；以及一開始我是打算print出來中文資訊的，後來發現中文好像顯示不出來，於是用起了我的蹩腳英文。
