Comparing two datetime objects There are a few ways to compare datetime objects. You may want to know whether one is greater than another, meaning if one came after the other. Or you might want to know how much time has passed between two datetime objects. In the first comparison, we are...
获取当前日期和时间 我们先看如何获取当前日期和时间： >>> from datetime import datetime >>> now =...
In this section, the code extracts the date portion from the DateTime objects and compares them using the standard comparison operators. Using the DateTime class, we’ve demonstrated how to compare two dates without considering their time information in Python. This approach is helpful when comparin...
datetime . utcnow () difference = ( dt - dt_utc ) . total_seconds () print ( 'Total difference: %.2f seconds' % difference ) This code could not be any simpler: we create two datetime objects, and calculate the difference. The problem is that we probably intended both now() and ...
Iterator is like range(11), compare to list = [0,1,...,10] all data is stored in memory. Iterator only generates values from looping through the object. # to get iterator from range function x = range(10) iter(x) x.__iter__() ...
Bar chart is used to simulate the changing trend of objects over time or to compare the figures / factors of objects. Bar charts usually have two axes: one axis is the object / factor that needs to be analyzed, the other axis is the parameters of the objects. ...

Since in Python it is required that objects that compare equal also have the same hash value (docs here), 5, 5.0, and 5 + 0j have the same hash value. >>> 5 == 5.0 == 5 + 0j True >>> hash(5) == hash(5.0) == hash(5 + 0j) True Note: The inverse is not necessarily...
