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. rounds a number to the number of decimal points you choose






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






3. unction to read one line of a file






4. 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






5. Prints a string to the screen which is converted using repr()






6. A built-in function that takes any value and converts it to an integer if possible - or complains otherwise.






7. Less than symbol






8. Function to open or read a file






9. asks the user for a response and returns that response






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






11. This statement causes an exception.






12. Evaluates to false if the variables on either side of the operator point to the same object and true otherwise. x is not y - here is not results in 1 if id(x) is not equal to id(y).






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






14. The extension for Python scripts






15. Prevents a runtime error from stopping the program.






16. Turns a line into a comment instead of executable code.






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






18. Prints a string to the screen which is converted using repr()






19. Greater than symbol






20. The keyword beginning a header that will create a new function.






21. Create a variable.






22. Greater than or equal symbol.






23. turns an object into an integer






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






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






26. Adds something to a variable






27. 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.






28. The keyword beginning a header that will create a loop.






29. floor division AND assignment operator






30. A built-in function that converts its argument to a string.






31. multiply AND assignment operator






32. The keyword beginning a header that will create a loop.






33. subtract AND assignment operator






34. Binary Left Shift Operator. The left operands value is moved left by the number of bits specified by the right operand. a << 2 will give 240 which is 1111 0000






35. absolute value






36. 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






37. Less than symbol






38. Modulus operator. It's the remainder after division






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






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






41. returns the length of a string (number of characters)






42. returns the length of a string (number of characters)






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






44. exponentiation






45. A data type for representing numbers with fractional values.






46. prints its parameter to the console






47. square root






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






49. ,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.






50. Argument variable
