重新读取一个打开的文件Python

要么

seek

with open(...) as fin:    fin.read()   # read first time    fin.seek(0)  # offset of 0    fin.read()   # read again

或再次打开文件（我更喜欢这种方式，因为否则您将使文件保持打开状态一个小时，而在两次通过之间不执行任何操作）

with open(...) as fin:    fin.read()   # read first timewith open(...) as fin:    fin.read()   # read again

放在一起

while True:    with open(...) as fin:        for line in fin: # do something     time.sleep(3600)
