This indicates there is a 31 day and 3-hour difference between the two timestamps. What if we just want to get a number back indicating a given unit of time? The variable type returned when we subtract one time from another is timedelta. The timedelta object has attributes for each unit...
2)Example 1: Calculate the Difference Between Two Dates in Years, Months & Days Format 3)Example 2: Calculate Your Lifetime 4)Video, Further Resources & Summary Let’s dive into it! Example Data & Add-On Libraries First we have to import date from thedatetime moduleand relativedelta from ...
panda通常面向处理日期数组(array of dates),无论这些日期是作为DataFrame的轴索引还是列。pandas.to_datetime函数可以解析多种不同的日期表示形式。像ISO 8601这样的标准日期格式可以非常快速地解析: pandas is generally oriented toward working with arrays of dates, whether used as an axis index or a column i...
The output confirms it's possible to subtract and addtimedeltaobjects. Multiplication and division are also possible: print("Multiply time interval by 3:")print(time_between_1_and_2*3)print("Divide time interval by 3:")print(time_between_1_and_2/3) ...

while the TimeDelta class represents the duration between two dates or times. Then we create the two DateTime objects to compare and subtract datetime1 from datetime2 to calculate their time difference. The result is a TimeDelta object, which we store in the time_difference variable. Next, we ...
