Please solve using python programming.

In Exercises 55 through 60, write a condition equivalent to the negation of the given condition. (For example, a! = b is equivalent to the negation of a == b.)

55. a > b

57. (a < b) and (c != d)

59. a <= b

In Exercises 61 through 68, simplify the expression. (In Exercises 63 through 68, assume that the variable has an integer value.)

61. (ans == 'Y') or (ans == 'y') or (ans == "Yes") or (ans == "yes")

63. (year == 2010) or (year == 2011) or (year == 2012) or (year == 2013) 

65. (n >= 3) and (n < 9) 

67. (n <= 10) and (n > 20) 

 Rewrite the following statement using the chr function instead of escape sequences.
