  • Python内置函数之str()

    class str(object="")
    class str(object=b'', encoding='utf-8', errors='strict')

    将其他对象转化为字符串对象。

    例子:

    >>> str(123)
    '123'
    >>> str()
    ''
    >>> file = open('data.txt','rb')
    >>> fb = file.read()
    >>> str(fb)
    "b'\xe5\xa4\xa9\xe7\x8e\x8b\xe7\x9b\x96\xe5\x9c\xb0\xe8\x99\x8e\xef\xbc\x8c\xe5
    \xb0\x8f\xe9\xb8\xa1\xe7\x82\x96\xe8\x98\x91\xe8\x8f\x87\xe3\x80\x82'"
    >>> str(fb,'utf-8') #指定编码集
    '天王盖地虎,小鸡炖蘑菇。'
    >>> str(fb,'gbk','ignore') #指定报错级别
    '澶╃帇鐩栧湴铏庯紝灏忛浮鐐栬槕鑿囥'
    >>> file.close()
