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






2. 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






3. Adds something to a variable






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






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






6. Prevents a runtime error from stopping the program.






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






8. This statement exits a function. The remaining lines of the function are not executed.






9. A logical operator which returns a value of True if either of the conditions is true.






10. floor division AND assignment operator






11. sets the file's current position






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






13. exponent AND assignment operator






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






15. Function to write something to a file






16. modulo






17. This keyword attempts to do something that would cause the program to crash if it were not for this statement.






18. empties the file






19. modulus AND assignment operator






20. adds an item to a list






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






22. Reads just one line of a text file.






23. 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).






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






25. unction to read one line of a file






26. deletes an item from a list






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






28. Function to read the contents of a file






29. floor division AND assignment operator






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






31. multiply AND assignment operator






32. A statement that assigns a value to a variable.






33. 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






34. square root






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






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






37. Symbol to multiply things






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






39. divide AND assignment operator






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






41. Greater than symbol






42. 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.






43. Symbol to subtract things from each other






44. Where the parameters go. A necessary punctuation after any function even if it's empty.






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






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






47. End header line.






48. deletes an item from a list






49. assignment operator






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