How do you prevent a while loop from becoming an infinite loop? How could internal documentation improve this program?
x = 90
a = 37
c = x/a
print(c)
You learned in this unit that Python requires your syntax to be strictly correct. For example, if you don’t indent a line after an if statement, your program will crash, and you will get an error message. Why do you think Python is designed with such strict rules? Would it be better if Python were more flexible? Why or why not?
Consider this program:
flavors = ["mild", "medium", "hot", "extra hot"]
choice = int(input("How many options do you want?"))
for i in range(choice):
print("You can order", flavors[i])
Can you anticipate a situation in which this program will crash? What could you do to prevent that situation from happening?
You learned in this lesson that you can use negative index numbers to access list items starting at the end of the list. In what situations might this be useful?

Budgets you to do all of the following expect a) send frivolously b) avoid over spending c) gain financial independence d) examine your priorities and goals

You need to design a circuit that implements the functions in the following table: s0 s1 function0 0 a + 10 1 a – b1 0 a + b1 1 a – 1s0 and s1 are 1-bit control inputs to select the function of the circuit. inputs a and b are 4-bitnumbers in 2s complement form. the output is also a 4-bit number in 2s complement form.you are allowed to use only one ttl 7483 4-bit adder to implement all the functions. but anynumber of other components (except the adder) can be used.hint: design a combinational logic circuit to modify the input b and the “carry input” of theadder depending on the control inputs s0 and s1.important: lab grade will depend on the working of the circuit & will be checked of by your labinstructor.1. is the output valid for the following input combinations: a. s0 = 0, s1 = 0, a = 7, b = 3? b. s0 = 0, s1 = 1, a = 7, b = 3? c. s0 = 1, s1 = 0, a = -4, b = -5? d. s0 = 1, s1 = 1, a = -8, b = 6? 2. what is the range of inputs (for both a and b) that will produce the valid output for all the functions?

Write the command that can be used to answer the following questions. (hint: try each out on the system to check your results.) a. find all files on the system that have the word test" as part of their filename. b. search the path variable for the pathname to the awk command. c. find all files in the /usr directory and subdirectories that are larger than 50 kilobytes in size. d. find all files in the /usr directory and subdirectories that are less than 70 kilobytes in size. e. find all files in the / directory and subdirectories that are symbolic links. f. find all files in the /var directory and subdirectories that were accessed less than 60 minutes ago. g. find all files in the /var directory and subdirectories that were accessed less than six days ago. h. find all files in the /home directory and subdirectories that are empty. i. find all files in the /etc directory and subdirectories that are owned by the group bin."
