Basic Python Programming

Subject : it-skills
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. returns the length of a string (number of characters)






2. multiply AND assignment operator






3. Reads the contents of the file you can assign the result to a variable.






4. Symbol to subtract things from each other






5. modulo






6. Binary Ones Complement Operator is unary and has the efect of 'flipping' bits. (~a ) will give -60 which is 1100 0011






7. exponent AND assignment operator






8. Binary AND Operator copies a bit to the result if it exists in both operands. (a & b) will give 12 which is 0000 1100






9. Symbol to multiply things






10. Adds something to a variable






11. Adds a new line character






12. This keyword begins the simplest form of a conditional statement.






13. ,multi-line comment hard-code,Fix (data or parameters) in a program in such a way that they cannot easily be altered by the user.






14. A string that begins with the % symbol and contains a sequence of printable characters and format specifiers that determine how values output should look.






15. adds an item to a list






16. Binary Right Shift Operator. The left operands value is moved right by the number of bits specified by the right operand. a >> 2 will give 15 which is 0000 1111






17. Prevents a runtime error from stopping the program.






18. This keyword in the body of a conditional allows chained conditionals.






19. Command to print to the screen






20. Evaluates to true if it does not finds a variable in the specified sequence and false otherwise. x not in y - here not in results in a 1 if x is a member of sequence y.






21. Symbol used to create comments






22. Less than or equal to symbol






23. Binary XOR Operator copies the bit if it is set in one operand but not both. (a ^ b) will give 49 which is 0011 0001






24. Evaluates to true if it finds a variable in the specified sequence and false otherwise. x in y - here in results in a 1 if x is a member of sequence y.






25. Binary XOR Operator copies the bit if it is set in one operand but not both. (a ^ b) will give 49 which is 0011 0001






26. Function to close a file - it will not be able to be used again unless the file is opened.






27. Function to read the contents of a file






28. Greater than symbol






29. exponent AND assignment operator






30. exponentiation






31. An operator that removes a value from a list.






32. Symbol used to create comments






33. Symbol to divide by the number to the right of the symbol






34. Greater than or equal symbol.






35. exponentiation






36. subtract AND assignment operator






37. This keyword begins a header for a body that repeats until the condition is no longer true.






38. assignment operator






39. unction to read one line of a file






40. A boolean operator that takes two strings and returns True if the first appears as a substring in the second.






41. Greater than symbol






42. Function to empty the contents of a file - no recovery is possible






43. deletes an item from a list






44. Binary OR Operator copies a bit if it exists in eather operand. (a | b) will give 61 which is 0011 1101






45. Function to close a file - it will not be able to be used again unless the file is opened.






46. This keyword in the body of a conditional - gives an alternative execution.






47. Prints a string to the screen which will be Unicode.






48. turns an object into a string






49. A logical operator which negates an expression so that it returns a value of True if the expression is false.






50. Holds the value of something - e.g. oh_hi = 4 where oh_hi is the variable.
