What is the correct syntax to output the type of a variable or object in Python?

Answers

Answer:

If a single argument (object) is passed to type() built-in, it returns type of the given object. If three arguments (name, bases and dict) are passed, it returns a new type object. If you need to check type of an object, it is recommended to use Python isinstance() function instead.

The correct syntax to find a variable type in python is type().

The type () function is used to return the data type or the type of variable. Inside the bracket you would have to input an object. The object could be a list, a string, a tuple, or an integer.

For example:

Lets say age = 50

Now we are to find out if the variable age is an, integer, a list, a tuple or a string. So we put the  variable age into the syntax.

type(age)

The output that would be returned is int. This tells us that the variable age is an integer. Because 50 is an integer.

Write a program to convert centigrade to Kelvin. It should display value in centigrade and then the value in Kelvin just as you displayed squares in the previous question. The range to be followed for this conversion is from 50-100 degree celsius.

So, it should look like this:
1. Centrigrade: 50 --> Kelvin: 323.15
2. Centrigrade: 51 --> Kelvin: 324.15
3. Centrigrade: 52 --> Kelvin: 325.15
etc.

Answers

Answer:

for degree in range(50, 101):

   kelvin = degree + 273.15

   print("Centrigrade: {} --> Kelvin: {}".format(degree, kelvin))

Explanation:

*The code is in Python.

Create a for loop that iterates from 50 to 100 (Note that the starting value is included, but the ending value is not included in the range method. That is why you need to write range(50, 101) to iterate from 50 to 100)

Convert the centigrade to kelvin using formula (Note that the degree variable represents the each centigrade degree from 50 to 100 and you need to add 273.15 to convert it to Kelvin)

Print the result as in requested format

Select all the steps needed to create a maintenance schedule. Identify individuals to perform the maintenance. Document or log maintenance that has been performed. Take an inventory of the equipment. Obtain test equipment if necessary. Define maintenance tasks. Review the manufacturers' manuals. Establish frequency of tasks. Run the defragmentation utility. Develop a reminder system.

Answers

Answer:

Maintenance planning and scheduling, arguably the most neglected functions of modern asset management, are at the heart of an effective maintenance management system. Through the use of work orders and a CMMS, maintenance planning covers the daily or weekly planning, scheduling and control activities to ensure that scheduled work is undertaken, and that available resources are being used optimally. Yet many organizations still struggle to make their maintenance planning and scheduling as effective as it should be.

Maintenance planning

Without planning and scheduling, the wrench-on time for a company is on average only 35%. That means that for every technician working an 8-hour day, only 2.8 hours of that day is spent working on assets. Implementing proper maintenance planning and scheduling, however, can increase the wrench time from 35% to 65%. At this level of efficiency, a technician working an 8-hour day will complete 5.2 hours of actual work. With 65% of the engineer’s time being used efficiently, only 35% of their time is wasted. This improvement would enable an organization to move away from a reactive (firefighting) state of maintenance, and improve overall workforce efficiency.

Explanation:

1. Identify the problem

The need for maintenance can be triggered by a failure, a noisy bearing or an oil leak. Once identified, the problem must be reported to the maintenance department. This is normally done through a work request so that planning and scheduling can take place.

2. Plan the maintenance task

‘Planning’ involves deciding on what exactly needs to be done, determining priority, and defining the sequence of activities and skills required. Ensure that all the resources, material, labor, contract services, specialist equipment, tools and information are available. There may even be a need for outside contractors, items to be purchased or work permits to be obtained, all of which must be arranged in advance.

A maintenance planning function is a critical tool for reducing downtime and maximising the value of preventive maintenance. The maintenance planner must therefore have the technical skills and equipment knowledge to do this planning.

3. Schedule the work

‘Scheduling’ involves deciding when to do the work. This will depend on the priority level of the task, and the availability of both the resources and the equipment to be repaired. Many organizations schedule maintenance for a specific period during the working week or month. Weekend maintenance is never desirable because, in many cases, suppliers are not available and personnel are expensive.

The legal requirements with regard to statutory inspections are generally quite rigid, so try and devise a 52-week maintenance plan at the beginning of each year. Review this plan periodically to improve the accuracy and quality of the information. Communicate the preventive and corrective maintenance requirements to production so that they fully understand the need for the maintenance window.

4. Allocate the task to specific people

Although this will depend on organizational arrangements, consider the following:

Allocate your maintenance personnel to specific areas or pieces of equipment

Ensure the allocated person has the skills to perform the task

Be very clear about the type of work that will be allocated to outside contractors

Where necessary, undertake hazard analyses to identify risks and formulate action plans to control access to high-risk areas; your plans should include hot work permits, confined space permits and lockout procedures.

5. Ensure the work is executed properly

It is usually the responsibility of the maintenance supervisor to confirm that the maintenance work meets the required quality standards, usually through selected planned job observations. The planner (or, in some instances, a maintenance scheduler) should monitor outstanding schedules or work requests to ensure that the planned work was actually done.

6. Analyze the problem and decide how to prevent it from happening again

Analyze the root cause of major failures and take corrective action to prevent recurrence. Corrective action could include training, a change to the preventive maintenance programme or equipment redesign. Breakdown or failure of the management process is often overlooked in a major failure. In those cases, corrective action may be a systems upgrade.

When all six of these foundational steps are implemented and combined correctly, maintenance planning can attain much greater levels of efficiency. This leads to important asset-related data and information being shared across the plant, and even across multiple plants. It’s not an overnight process though, so don’t give up if you think it might take too long. The benefits are well worth it.
