If it is an integer, the array will have that size and will be initialized with null bytes. If it is an object conforming to the buffer interface, a read-only buffer of the object will be used to initialize the
Return a new array of bytes. The bytearray class is a mutable sequence of integers in the range 0 <= x < 256. It has most of the usual methods of mutable sequences, described in Mutable Sequence Types, as well as most methods that the bytes type has, see Bytes and Bytearray Operati...
char数组和Python字符串的Python列表是两个非常不同的东西。 如果你想要一个包含char数组(一个字符串)的分支,那么我建议使用Python的内置bytearray类型: import ROOT # create an array of bytes (chars) and reserve the last byte for null # termination (last byte remains zero) char_array = bytearray(21...
array.find(b"c")) # 对元素b'c'使用len方法 print("Count of bytes:",
