In this article, we are going to discuss how to print current hour, minute, second, and microsecond using Python. In order to print hour, minute and microseconds we need to use DateTime module in Python.
Methods used
- datetime.now().hour(): This method returns the current hour value of the datetime object.
- datetime.now().minute(): This method returns the current minute value of the datetime object.
- datetime.now().second(): This method returns the current second value of the datetime object.
- datetime.now().microsecond(): This method returns the current microsecond value of the datetime object.
Below are the various implementations using examples that depict how to print current hour, minute, second, and microsecond in python.
Example 1: To print time, hour, minute, second, and microsecond
Python3
# importing datetime modulefrom datetime import datetime# now is a method in datetime module is# used to retrieve current data,timemyobj = datetime.now()# printing current hour using hour# classprint("Current hour ", myobj.hour)# printing current minute using minute# classprint("Current minute ", myobj.minute)# printing current second using second# classprint("Current second ", myobj.second)# printing current microsecond using# microsecond classprint("Current microsecond ", myobj.microsecond) |
Current hour 4 Current minute 5 Current second 13 Current microsecond 121302
Time complexity: O(1) – constant time complexity, since the code is only retrieving and printing the current time values.
Auxiliary space: O(1) – constant space complexity, since the code is not using any additional data structures or variables that increase with input size.
Example 2: To print object, time, hour, minute, second, and microsecond.
Python3
# importing datetime modulefrom datetime import datetime# now is a method in datetime module is# used to retrieve current data,timemyobj = datetime.now()# printing the object itselfprint("Object:", myobj)# printing current hour using hour# classprint("Current hour ", myobj.hour)# printing current minute using minute# classprint("Current minute ", myobj.minute)# printing current second using second# classprint("Current second ", myobj.second)# printing current microsecond using microsecond# classprint("Current microsecond ", myobj.microsecond) |
Object: 2022-11-24 04:07:13.707730 Current hour 4 Current minute 7 Current second 13 Current microsecond 707730
Time Complexity: O(1)
Auxiliary Space: O(1)
Approach#3: Using time module
We can use the built-in time module in Python to get the current time. We can use the time() function of the time module to get the number of seconds and then extract the hour, minute, second, and microsecond components from it.
Algorithm
1. Import the time module.
2. Call the time() function of the time module to get the current time.
3. Convert the current time to a struct_time object using the localtime() function of the time module.
4. Extract the hour, minute, second, and microsecond components from the struct_time object.
5. Print the extracted components.
Python3
import timecurrent_time = time.time()local_time = time.localtime(current_time)hour = local_time.tm_hourminute = local_time.tm_minsecond = local_time.tm_secmicrosecond = int((current_time - int(current_time)) * 1000000)print('current hour' ,hour)print('current minute' ,minute)print('current second ',second)print('current microsecond ', microsecond) |
current hour 10 current minute 48 current second 50 current microsecond 397817
Time complexity: O(1)
Auxiliary Space: O(1)
Approach#4: Using strftime()
Use the time module to get the current time in seconds since the Epoch. Use the strftime function to format the time into hours, minutes, seconds, and microseconds. Convert the fractional part of the seconds into microseconds by subtracting the integer part and multiplying by 1,000,000. Print the formatted time.
Algorithm
1. Get the current time in seconds since the Epoch using time.time() function.
2. Use the time.strftime() function to convert the current time into the desired format.
3. Convert the fractional part of seconds into microseconds.
4. Print the formatted time.
Python3
import timenow = time.time()hour, minute, second = time.strftime('%H'), time.strftime('%M'), time.strftime('%S')microsecond = int((now - int(now)) * 1000000)print(f"Current hour: {hour}")print(f"Current minute: {minute}")print(f"Current second: {second}")print(f"Current microsecond: {microsecond}") |
Current hour: 05 Current minute: 17 Current second: 27 Current microsecond: 760716
Time complexity: O(1), as all operations take constant time.
Auxiliary Space: O(1), as we only store a few variables that have constant size.
