# 1.直接替換不需要的符號，在使用精靈函數切割

print(string.replace(‘,‘, ‘ ‘).replace(‘?‘, ‘ ‘).replace(‘.‘, ‘ ‘).split())

# 2.依次查找函數中不需要的符號，與列表對比後替換，在使用精靈函數切割

def st(text, list):
    for i in list:
        text = text.replace(i, ‘‘)
    print(text.split())


st(string, [‘,‘, ‘?‘, ‘.‘])

結果：

[‘i‘, ‘am‘, ‘a‘, ‘chinese‘, ‘boybut‘, ‘she‘, ‘is‘, ‘a‘, ‘japanese‘, ‘girlshe‘, ‘is‘, ‘russia‘, ‘girlplease‘, ‘tell‘, ‘me‘, ‘that‘, ‘how‘, ‘do‘, ‘i‘, ‘choiceand‘, ‘can‘, ‘we‘, ‘happyniesscan‘, ‘we‘, ‘happyniess‘]

【面試】Python字符切割，replace+split
