For Loop Challenges

Write a for loop so that every item in the list is printed.

lst=["koala", "cat", "fox", "panda", "chipmunk", "sloth", "penguin", "dolphin"]
#Type your answer here.
for x in lst:
    print(x)

koala
cat
fox
panda

sloth
penguin
dolphin

Write a for loop which print "Hello!, " plus each name in the list. i.e.: "Hello!, Sam"

#Type your code here.
for x in lst:
    print("hello!,")
    print (x)

hello!,
Sam
hello!,
Lisa
hello!,
Micha
hello!,
Dave
hello!,
Wyatt

Write a for loop that iterates through a string and prints every letter.

str="Antarctica"
#Type your code here.
for x in "Antarctica":
    print(x)

A
n
t
a
r
c
t
i
c
a

Type somecode 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

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

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=["dr"]

#Type your answer here.
for x in lst2:
  for y in lst1:
    print(x, y)

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 i in lst1:
    lst2.append(i**2)
    print(lst2)

[9]
[9, 49]
[9, 49, 36]
[9, 49, 36, 64]
[9, 49, 36, 64, 81]
[9, 49, 36, 64, 81, 121]
[9, 49, 36, 64, 81, 121, 225]
[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.
for i in lst1:
    if i > 0:
        lst2.append(i)
print(lst2)

[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 i in lst1:
    lst2.append(type(i))
print(lst2)

[<class 'float'>, <class 'int'>, <class 'str'>, <class 'bool'>, <class 'list'>, <class 'dict'>]
