Python's time module source shows that are based on time. The time() method is used by developers and returns the current time as a UNIX timestamp. A UNIX timestamp is converted into a typical year, month, day, and time format using the ctime() function.
Time management is a crucial component of many programmes. Consider creating a website sign-up form as an example. To find out when a user registered for your website, you might wish to get the current time.
The Python time module can be used in this situation. You can work with time in your Python scripts thanks to the time module. You have the option to take actions like getting the current time and pausing the application.
Import statements for Python
You may import a module into your code using the Python import statement. A module is a file that has variables and functions you may use in your application. The syntax for an import statement is import modulename.
A variety of constructed modules in Python enable you to carry out routine activities in your code. For instance, the int() function turns a value into an integer. sum() determines the total value of every item in a list.
Even while these functions have their uses, you might wish to develop their own that could be applied across your entire codebase. Python modules come into play here.
How to Use the import Statement in Python
Code from one module is imported into another programme using the import command in Python. By using the import keyword after the module you wish to import, you may import all the code from that module.
In a Python file, import statements are found above any possible comments. This is due to the fact that importing modules or packages at the beginning of a file clarifies the organisation of your code.
The import statement's syntax is as follows:
Let's examine a Python import statement example.
The following commands might be used to import the sys library:
Example of a Python import Module
Let's say we wish to add the time module to an application. We don't have to install the time module into our code as it is a component of the Python Standard Library.
The following code might be used to import the module:
We may utilize this modules in our code once it has been imported. We imported time into our code in the aforementioned example so we were able to access the all time methods in our main application.
We must cite the specific module namespace in order to use the code included in a module. Using the dot notation will allow us to do this.
Let's say we wish to use the time module's sleep() method. This code would allow us to achieve that:
The time module is imported first. When Python imports a module, it locates the module's code in the standard library.
After then, "time.sleep" is used to refer to the time library's sleep() method. In dot notation, the module name is named first, then the name of the function we wish to access is followed by a dot.
The programme will end when our code has waited six seconds.
import Python: Include Multiple Modules
We have only imported one module into our code thus far. However, we are free to import any number of modules.
Let's say we wish to import the Python Standard Library's time and random modules into our programme. This code would allow us to achieve that:
We may utilise the Python functions from these modules in our code now that we have imported them. Let's say we want to retrieve the current time first, then produce a random number between 1 and 5. With the help of this programme, we could:
timestamp = time.time()
current_time = time.ctime(timestamp)
The "time" and "random" modules are initially imported. The random.randint() method is then used to produce a random integer. The current time is then retrieved and printed to the terminal using the same code as in our earlier example.
To obtain the present time as a floating-point value in seconds since the epoch, use the time.time() method.
This function produces a floating-point number that indicates the number of seconds since January 1, 1970, 00:00:00, together with the present timestamp.
It gives back the current time in format seconds.microseconds.
# get the time right now in seconds.
t = time.time()
We can get the current time using ctime() in python:
Most people cannot read epoch time. Using the Python ctime() method, you may modify the time from of the epoch to local time.
One parameter can be sent to the ctime() method. This function returns a string containing the local time and accepts as an argument the number of seconds since the epoch began. This number is determined by the time zone of the computer.
Let's say we wish to change the floating-point value from the previous epoch into a timestamp. With the aid of this software, we could:
epoch_time = 1556934163.152886
local_time = time.ctime(epoch_time)
print("The local time is:", local_time)
