for x in "Antarctica":
    print(x)

A
n
t
a
r
c
t
i
c
a

Type some code inside the for loop so that counter variable named c is increased by one each time loop iterates. Can you guess how many times it will add 1?.

str="Civilization"

c=0
for i in str:
    #sourcecode will go below
    c=c+1
print(c)
    #sourcecode will go above

Using a for loop and .append() method append each item with a Dr. prefix to the lst.

Info on the .append() method can be found at https://www.w3schools.com/python/ref_list_append.asp

lst1=["Phil", "Oz", "Seuss", "Dre"]
lst2=[]

#Type your answer here.
for x in lst1:
    print ("Dr. {}" .format (x))
    lst2.append(lst1)

Dr. Phil
Dr. Oz
Dr. Seuss
Dr. Dre

Write a for loop which appends the square of each number to the new list.

lst1=[3, 7, 6, 8, 9, 11, 15, 25]
lst2=[]
#Type your answer here.
for x in lst1:
    print ("{}" .format (x**2))
    lst2.append(lst1)

9
49
36
64
81
121
225
625

Write a for loop using an if statement, that appends each number to the new list if it's positive.

lst1=[111, 32, -9, -45, -17, 9, 85, -10]
lst2=[]
#Type your answer here.
lst2.append(lst1)
for x in lst1:
    if x >= 0:
        print ("{}" .format (x))

111
32
9
85

Write a for loop which appends the type of each element in the first list to the second list.

lst1=[3.14, 66, "Teddy Bear", True, [], {}]
lst2=[]

#Type your answer here.
for x in lst1:
    print ("{}" .format(type(x)))
    lst2.append(lst1)
