Answer:

The solution code is written in Python 3 as below:

  1. outfile = open("greeting.txt", "w")
  2. outfile.write("Hello World")
  3. outfile.close()

Explanation:

To create a simple text file in Python, we can use Python built-in function, <em>open()</em>. There are two parameters needed for the open() function,

  1. the file name and
  2. a single keyword "w". "w" denote "write". This keyword will tell our program to create a file if the file doesn't exist.

The statement <em>open("greeting.txt", "w")</em> will create a text file named "<em>greeting.txt</em>" (Line 1)

To fill up the content in the greeting.txt, we use <em>write()</em> method. Just include the content string as the argument of the <em>write()</em> method. (Line 2)

At last, we use <em>close() </em>method to close the opened file,<em> outfile</em>. This will release the system resource from the<em> outfile.</em>

Complete the function ending_time that determines the final clock time after a task has been completed. The function takes three
Ivanshal [37]

Answer:

  1. def ending_time(hour, minutes, seconds, work_time):
  2.    if((seconds + work_time) // 60 > 0):
  3.        minutes = minutes + (seconds + work_time) // 60
  4.        seconds = (seconds + work_time) % 60    
  5.        if(minutes // 60 > 0):
  6.            hour = hour + (minutes // 60)
  7.            minutes = minutes % 60
  8.    else:
  9.        seconds = seconds + work_time  
  10.    return str(hour) + ":" + str(minutes) + ":" + str(seconds)
  11. print(ending_time(2,30,59, 12000))

Explanation:

The solution code is written in Python 3.

Firstly create a function ending_time that takes the four required input parameters.

Next, create an if statement to check if the numerator of (seconds + work_times) divided by 60 is over zero. If so, increment the minute and reassign the remainder of the seconds to the variable (Line 2-4).

Next, create another if statement again to check if the numerator of (current minutes) divided by 60 is over zero, if so increment the hour and reassign the remainder of the minutes to the variable (Line 6-8)

Otherwise, just simply add the work_time to the current seconds

At last return the time output string (Line 12).
