Python:两个time.time()之间的减法值是多少？

Question

import time

print time.time() - time.time()

结果单位是millisecond或second？

我想做的是判断两个操作时间跨度是否大于10分钟

Answer 1

返回自纪元以来的秒数作为浮点数.(来自文件)

因此,两次之间的差异也是秒.

time_a = time.time()

# ... some operations ...

ten_minutes =  10 * 60
time_span = time.time() - time_a
if time_span > ten_minutes:
    # time span is larger than 10 minutes.
