python计算两个时间的时间差

from datetime import datetime
# Define the start time and end time as strings
start_time_str = "2023-07-20 10:30:00"  # Replace with your start time string
end_time_str = "2023-07-22 15:45:00"  # Replace with your end time string
# Convert the time strings to datetime objects
start_time = datetime.strptime(start_time_str, "%Y-%m-%d %H:%M:%S")
end_time = datetime.strptime(end_time_str, "%Y-%m-%d %H:%M:%S")
time_difference1 = (end_time - start_time)
print(time_difference1)
# Calculate the time difference
time_difference = (end_time - start_time).total_seconds()
# Print the time difference
print(f"Time Difference: {time_difference/60/60/24}")
print(0.21875*24)
print(0.25*60)

输出结果如下所示：
