Python Pre-Course Questions

"# .py" "# .py" Question 1 Write a function to print "hello_USERNAME!" USERNAME is the input of the function. The first line of the code has been defined as below.

def hello_name(user_name):

name="USERNAME" print('"hello_ ' + name + '"')

Question 2 Write a python function, first_odds that prints the odd numbers from 1-100 and returns nothing

def first_odds():

list1 = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 100] i = 0 while(i < len(list1)): if list1[i] % 2 != 0: print(list1[i], end=" ") i += 1

Question 3 Please write a Python function, max_num_in_list to return the max number of a given list. The first line of the code has been defined as below.

def max_num_in_list( list ):
max = list[ 0 ]
for a in list:
if a > max:
max = a
return max
print(max_num_in_list([6, 12, 28, 60]))

Question 4 Write a function to return if the given year is a leap year. A leap year is divisible by 4, but not divisible by 100, unless it is also divisible by 400. The return should be boolean Type (true/false).

def is_leap():
leap = False
if (year % 4 == 0 and year % 100 != 0) or year % 400 == 0:
    leap = True
return leap

Question 5 Write a function to check to see if all numbers in list are consecutive numbers. For example, [2,3,4,5,6,7] are consecutive numbers, but [1,2,4,5] are not consecutive numbers. The return should be boolean Type.

def checkConsecutive(l):
n = len(l) - 1
return (sum(np.diff(sorted(l)) == 1) >= n)
