<h2>I'm not sure but tell me if its right or wrong in order to help others</h2>
Explanation:
Hello! The answer to your question would be as followed:
C. The columns will be listed in the results in the same order they are listed in the SELECT clause of the SELECT statement.
Take this one step at a time. Your teacher has given you the code for step 1. Now write step 2. Then 3, and so on.
For step 2: if you're using Python v2.x you'd use a line like
guess = int( raw_input( "Take another guess: " ) )
For Python v3.x it would be:
guess = int( input( "Take another guess: " ) )
Break it down into small pieces, it's not a complicated assignment.
Answer:
The display output specifies the variable's data type and returns output line by line. The print output, on the other hand, does not indicate the variable's data type and does not deliver output line by line. The print output can be used to portray any type of data, such as a string or an approximate value. The display output is a Python programming capability that is used to comprehend a line of text given by the user.
Answer: Laser Beams
Explanation:
The laser beam is one of the type of technology that helps in amplifying the light by using the laser principle Stimulated emission in the laser. The word "LASER" is stand for the Light amplification by stimulated emission of radiation.
The laser is one of the device that emitted the coherent light in the form of beam rays that is propagate only in one direction. The following are the laser beam technology are as follows:
- Bar code reader
- Laser surface modification
- Information processing
- Laser range
Therefore, Laser beam is the correct answer.
