Help on timedelta object:
class timedelta(builtins.object)
| Difference between two datetime values.
|
| timedelta(days=0, seconds=0, microseconds=0, milliseconds=0, minutes=0, hours=0, weeks=0)
|
| All arguments are optional and default to 0.
| Arguments may be integers or floats, and may be positive or negative.
|
| Methods defined here:
|
| __abs__(self, /)
| abs(self)
|
| __add__(self, value, /)
| Return self+value.
|
| __bool__(self, /)
| self != 0
|
| __divmod__(self, value, /)
| Return divmod(self, value).
|
| __eq__(self, value, /)
| Return self==value.
|
| __floordiv__(self, value, /)
| Return self//value.
|
| __ge__(self, value, /)
| Return self>=value.
|
| __getattribute__(self, name, /)
| Return getattr(self, name).
|
| __gt__(self, value, /)
| Return self>value.
|
| __hash__(self, /)
| Return hash(self).
|
| __le__(self, value, /)
| Return self<=value.
|
| __lt__(self, value, /)
| Return self<value.
|
| __mod__(self, value, /)
| Return self%value.
|
| __mul__(self, value, /)
| Return self*value.
|
| __ne__(self, value, /)
| Return self!=value.
|
| __neg__(self, /)
| -self
|
| __pos__(self, /)
| +self
|
| __radd__(self, value, /)
| Return value+self.
|
| __rdivmod__(self, value, /)
| Return divmod(value, self).
|
| __reduce__(...)
| __reduce__() -> (cls, state)
|
| __repr__(self, /)
| Return repr(self).
|
| __rfloordiv__(self, value, /)
| Return value//self.
|
| __rmod__(self, value, /)
| Return value%self.
|
| __rmul__(self, value, /)
| Return value*self.
|
| __rsub__(self, value, /)
| Return value-self.
|
| __rtruediv__(self, value, /)
| Return value/self.
|
| __str__(self, /)
| Return str(self).
|
| __sub__(self, value, /)
| Return self-value.
|
| __truediv__(self, value, /)
| Return self/value.
|
| total_seconds(...)
| Total seconds in the duration.
|
| ----------------------------------------------------------------------
| Static methods defined here:
|
| __new__(*args, **kwargs) from builtins.type
| Create and return a new object. See help(type) for accurate signature.
|
| ----------------------------------------------------------------------
| Data descriptors defined here:
|
| days
| Number of days.
|
| microseconds
| Number of microseconds (>= 0 and less than 1 second).
|
| seconds
| Number of seconds (>= 0 and less than 1 day).
|
| ----------------------------------------------------------------------
| Data and other attributes defined here:
|
| max = datetime.timedelta(days=999999999, seconds=86399, microseconds=9...
|
| min = datetime.timedelta(days=-999999999)
|
| resolution = datetime.timedelta(microseconds=1)

import requests
test = requests.get('https://www.qq.com')
help(test.elapsed)
print(test.elapsed.seconds)
print(test.elapsed.days)
print(test.elapsed.min)
print(test.elapsed.max)
print(test.elapsed.total_seconds())
print(test.elapsed.microseconds)
print(test.elapsed.resolution)
返回结果：
0
0
-999999999 days, 0:00:00
999999999 days, 23:59:59.999999
0.071056
71056
0:00:00.000001
- 小结
网上提出获取接口响应时间均为：test.elapsed.microseconds/(1000*1000)，但是该种方式有个缺点（当接口的响应时间大于1s时，仅会截取后面的小数位）
所以推荐使用：test.elapsed.total_seconds()，准确性较高，单位为s
注：1 秒(second)[s] = 1000 毫秒millisecond[ms] = 1000000 微秒microsecond[us]
