Complete the process_name() function that takes a single string parameter name. You can assume that the name will always be in the format first name surname with a single space character between the first name and the surname. The function returns a string consisting of the first letter of the first name followed by the first three letters of the surname. All of the characters in the returned string should be in lowercase. Some examples of the function being used are shown below: For example: Test Result print(process_name("Damir Azhar")) dazh print(process_name("Ann Cameron")) acam Answer: (penalty regime: 0 %) Reset answer 1v def process_name (name): 2
***in python only*** use turtle function Define the concentricCircles function such that: It draws a series of concentric circles, where the first parameter specifies the radius of the outermost circle, and the second parameter specifies the number of circles to draw. The third and fourth parameters specify an outer color and an other color, respectively. The outer color is used for the largest (i.e., outermost) circle, and then every other circle out to the edge alternates between that color and the 'other' color. The difference between the radii of subsequent circles is always the same, and this difference is also equal to the radius of the smallest circle. Put another way: the distance between the inside and outside of each ring is the same. Define concentricCircles with 4 parameters Use def to define concentricCircles with 4 parameters Use any kind of loop Within the definition of concentricCircles with 4 parameters, use any kind of loop in at least one place.

Can you show the example output?
Can you write a new code in C ++ language with the values I sent you, just like this output? There are two files named group1.txt and group2.txt that contain course information and grades of each student for each class. I will calculate each course average for each group and show in simple bar graph. Use "*" and "#"characters for group1 and group2, respectively. I will see the number -999 at the end of each line in the input files. This value is used for line termination and you can use it to verify that you have arrived at the end of the line. The averages of each group should also be calculated and printed at the end of the file. All of the results will be printed to the file. There will be no screen output. Sample output is shown in Figure 1.
