Explanation:

The process of writing computer instructions in a programming language is known as Coding.

A computer program is usually written by a computer programmer in a programming language. From the program in its human-readable form of source code, a compiler can derive machine code—a form consisting of instructions that the computer can directly execute.

That line of code is written in the Python programming language. Put simply, a programming (or coding) language is a set of syntax rules that define how code should be written and formatted. Thousands of different programming languages make it possible for us to create computer software, apps and websites.

In programming, code (noun) is a term used for both the statements written in a particular programming language - the source code , and a term for the source code after it has been processed by a compiler and made ready to run in the computer - the object code .

Convert the decimal number 164 into the equivalent 8 bit binary number.

Answer:

10100100

Explanation:

8 bit system consists of 8 bits or 8 positions and each of them can have binary value (0 or 1).

Each bit is equivalent to a certain power of number 2. Important to know is that you read these bits from right to left.

So, this means that the bit furthest to the right has the value of 2^0, which is 1. The bit to the left has the value of 2^1, which is 2. Next one is 2^2, which is 4 etc. This means that the bit furthest to the left has the value of 2^7, which is 128.

The bit has this potential value only if value 1 if is in its position. If the value is 0 then, regardless of position, value of the bit is 0.

Decimal value of the number is calculated when we add all the values of the bits marked with 1.

So, we're dealing with number 164. We already said that leftmost bit has the value of 128 if it's marked with 1:

1 0 0 0 0 0 0 0 = 128

Next bit has the value of 64, but 128+64 would exceed the value of our number, so the second leftmost bit remains 0.

Next bit has the value of 32, 128+32 is 160, which is less then our number, so we mark the third bit with 1:

1 0 1 0 0 0 0 0 = 160

Similarly, we continue down the line. We only need 4 to reach the value of our number, so we'll mark with 1 the bit that has the value of 4, which leaves us with the solution:

1 0 1 0 0 1 0 0 = 164

Write code that does the following: opens an output file with the filename number_list.txt, uses a loop to write the numbers 1 t

Lady_Fox [76]

Answer:

# create the file

filename = "Testfile.txt"

# for writing, we create the output file:

outPutfile = open(filename, "w")

# Writing numbers from 1-100

for item in range(1,101):

outPutfile.write((str)(item))

outPutfile.close()

# printing the contents to verify it worked correctly

infile = open(filename, "r") #note the "r" indicates the mode

fileContents = infile.read()

infile.close()

print(fileContents)

Explanation:

Define the working file fileName = TestFile
Create the output file for writting outPutfile = open(filename, "w")
Use a for loop to write numbers from 1-100 to the file outPutfile.write((str)(item))
Close the file outPutfile.close()
You may open the file read its content and print the contents to verify it worked correctly
