Define a function allEqual of type ''a list -> bool that will return true will all element in the input list are all equal, false otherwise. If the input list is empty or is a singleton list, the function should return true. For example,

Follows are the code to this question:

def allEqual(l):#defining a method allEqual that accepts a parameter  

   if len(l)==0:#defining if block that check list length equal to 0

       return True#return true value

   x=set(l) #defining x variable that set of given list

   if len(x)!=1: #defining if that check x is not equal to 1  

       return False#return False

   return True#return True

print(allEqual([]))#Use print method to call method and print value

print(allEqual(["aa"]))#Use print method to call method and print value  

print(allEqual(["aa", "aa", "aa"]))#Use print method to call method and print value  

print(allEqual(["aa", "aa", "ab"]))#Use print method to call method and print value

print(allEqual([1,1,3, 1]))#Use print method to call method and print value

Output:

True

True

True

False

False

Explanation:

In the above-given code a method "allEqual" is defined that accept and a list in its parameter and inside the method a conditional statement is used that can be defined as follows:

In if block, it checks the length of the list which is equal to 0, it will return 0.

In the next step, an "x" variable is declared, that uses the set method to hold list value and use if block to check length not equal to 1 and return false, or method returns a value that is equal to true.

the benefits of raising bc’s minimum wage to $15 through a

series of pre-announced staged increases far outweigh the likely

costs. claims that such an increase will lead to massive job losses

in low-wage sectors of the economy are not credible.

• an increase to $15 would result in some job losses. however,

the likely impact is less than a 1 per cent reduction in the overall

provincial employment rate, and a 7.6 per cent reduction in the

employment rate for those currently making between $10.25

and $15 per hour.

• the large job loss impacts predicted by some opponents of

minimum wages misrepresent the existing economic research. in

reading and using that research, it is important to recognize that

estimates showing job loss effects of minimum wage increases

apply only to teenagers. estimated effects for young adult and

adult workers range from insignificant to non-existent.

• focusing on teenage workers plays up an inaccurate stereotype

about who earns very low wages in bc and leads to exaggerated

claims about job losses. only 26 per cent of those currently making

between $10.25 and $12 are teenagers, and only 5 per cent

of those making between $12 and $15 are teenagers.
