一个文本文件test.txt的一行存储5个整数如下：1 3 56 67 34数之间用空格隔开，要读出这些整数的函数正确的是：
A. def read(): f=open("test.txt","rt") while True: s=f.read() if s!="": print(s) else: break f.close()
B. def read(): f=open("test.txt","rt") while True: s=f.readline() if s!="": print(s) else: break f.close()
C. def read(): f=open("test.txt","rt") st=f.readlines() for s in st: print(s) f.close()
D. def read(): f=open("test.txt","rt") s=f.readline() st=s.splist(" ") for s in st: print(s) f.close()
如下选项中,不是Python对文件的读操做方法的是
A. readline
B. readlines
C. readtext
D. read
