Python ctime to datetime

How to convert `ctime` to `datetime` in python?

The built-in `ctime` function in Python returns a string representing the current time in a human-readable format, such as «Mon Jan 27 11:14:10 2023». However, it is not as flexible as the `datetime` module in Python, which provides more advanced features and functionalities for working with dates and times. If you need to convert the `ctime` string to a `datetime` object, there are several methods to do so.

Method 1: Using strptime

Here’s how you can convert a ctime string to a datetime object in Python using strptime :

from datetime import datetime ctime_string = 'Mon Sep 20 14:30:00 2021' datetime_object = datetime.strptime(ctime_string, '%a %b %d %H:%M:%S %Y') print(datetime_object)

Here’s what’s happening in the code above:

1. We import the datetime module.
2. We define a ctime_string variable with the ctime string we want to convert.
3. We use the strptime method to convert the ctime_string to a datetime object.
4. The first argument to strptime is the ctime_string we want to convert.
5. The second argument to strptime is a format string that specifies the format of the ctime_string .
6. %a represents the abbreviated weekday name.
7. %b represents the abbreviated month name.
8. %d represents the day of the month as a zero-padded decimal number.
9. %H represents the hour (24-hour clock) as a zero-padded decimal number.
10. %M represents the minute as a zero-padded decimal number.
11. %S represents the second as a zero-padded decimal number.
12. %Y represents the year with century as a decimal number.
13. We print the datetime_object to verify that the conversion was successful.

That’s it! You now know how to convert a ctime string to a datetime object in Python using strptime .

Method 2: Using datetime.datetime.fromtimestamp

To convert ctime to datetime in Python, you can use the datetime.datetime.fromtimestamp method. This method returns a datetime object corresponding to a POSIX timestamp, which is the number of seconds since January 1, 1970, 00:00:00 (UTC).

Here’s an example code snippet that demonstrates how to convert a ctime string to a datetime object using datetime.datetime.fromtimestamp :

import time from datetime import datetime ctime_str = 'Sat Jul 24 15:48:24 2021' ctime_tuple = time.strptime(ctime_str, '%a %b %d %H:%M:%S %Y') posix_timestamp = time.mktime(ctime_tuple) datetime_obj = datetime.fromtimestamp(posix_timestamp) print(datetime_obj)

In this example, we first convert the ctime string to a time tuple using the time.strptime method with the appropriate format string. We then convert the time tuple to a POSIX timestamp using the time.mktime method. Finally, we use the datetime.datetime.fromtimestamp method to convert the POSIX timestamp to a datetime object.

Here’s another example that demonstrates how to convert a list of ctime strings to a list of datetime objects using a list comprehension:

import time from datetime import datetime ctime_list = ['Sat Jul 24 15:48:24 2021', 'Sun Jul 25 12:30:00 2021', 'Mon Jul 26 09:15:30 2021'] datetime_list = [datetime.fromtimestamp(time.mktime(time.strptime(ctime_str, '%a %b %d %H:%M:%S %Y'))) for ctime_str in ctime_list] print(datetime_list)

In this example, we use a list comprehension to iterate over the ctime strings in the ctime_list and convert each one to a datetime object using the same method as before.

Overall, the datetime.datetime.fromtimestamp method is a convenient way to convert ctime strings to datetime objects in Python.

Method 3: Using datetime.datetime.strptime

here’s how you can convert ctime to datetime in python using datetime.datetime.strptime :

import datetime ctime_string = 'sat jul 24 17:15:55 2021' datetime_obj = datetime.datetime.strptime(ctime_string, '%a %b %d %h:%m:%s %y') print(datetime_obj) datetime_string = datetime_obj.strftime('%y-%m-%d %h:%m:%s') print(datetime_string)

in this code, we first import the datetime module. then, we define a variable ctime_string which contains the ctime string we want to convert.

next, we use the datetime.datetime.strptime method to convert the ctime string to a datetime object. the strptime method takes two arguments: the first is the string to be converted, and the second is a format string that specifies how the string should be interpreted. in this case, we use the format string ‘%a %b %d %h:%m:%s %y’ to match the format of the ctime string.

after we have the datetime object, we can print it out to verify that the conversion was successful.

finally, we use the strftime method to convert the datetime object back to a string in a different format. in this case, we use the format string ‘%y-%m-%d %h:%m:%s’ to produce a string in the format yyyy-mm-dd hh:mm:ss .

that’s it! this code should give you a good starting point for converting ctime strings to datetime objects in python using datetime.datetime.strptime .

How to convert `ctime` to `datetime` in Python?

You should use strptime : this function parses a string representing a time according to a format. The return value is a struct_time.

The format parameter defaults to %a %b %d %H:%M:%S %Y which matches the formatting returned by ctime().

So in your case just try the following line, since the default format is the one from ctime:

import datetime import time datetime.datetime.strptime(time.ctime(), "%a %b %d %H:%M:%S %Y") 

Returns: datetime.datetime(2012, 4, 21, 4, 22, 00)

Convert the ‘time.ctime()’ to datetime

time.ctime() by default returns a string. you can just format this as shown in the other answers

 import datetime import time from time import strptime # Print the ctime -- Result type is already a string a = time.ctime() print("\n\tToday's date: <> Type: <>\n".format(a, type(a))) print("\n\tToday's date: <> Type: <>\n".format(time.ctime(), type(time.ctime()))) # just convert that to a datetime c = datetime.datetime.strptime(a, "%a %b %d %H:%M:%S %Y") print("\n\tToday's date: <> Type: <>\n".format(c, type(c))) # %a - abbreviated weekday name # %b - abbreviated month name # %d - day of the month (01 to 31) # %H - hour, using a 24-hour clock (00 to 23) # %M - minute # %S - second # %Y - year including the century d = datetime.datetime.strptime(a, "%c") print("\n\tToday's date: <> Type: <>\n".format(d, type(d))) # %c - preferred date and time representation # Results: # Today's date: Fri Apr 22 15:50:17 2022 Type: # Today's date: Fri Apr 22 15:50:17 2022 Type: # Today's date: 2022-04-22 15:50:17 Type: # Today's date: 2022-04-22 15:50:17 Type:
