For Loop challenges!!

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

Ihatejesus=["koala", "cat", "fox", "panda", "chipmunk", "sloth", "penguin", "dolphin"]
#Type your answer here.
print (Ihatejesus)

['koala', 'cat', 'fox', 'panda', 'chipmunk', '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 item in item:
    print ("Hello, {}!".format(item))

Hello, Sam!
Hello, Lisa!
Hello, Micha!
Hello, Dave!
Hello, Wyatt!
Hello, Emma!
Hello, Sage!

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

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

A

c
t

Type a 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"
#Type your answer here. 
c=0
for letterc  in str:
    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=[]
#Type your answer here.
for name in lst1:
    lst2.append("Dr. {}".format(name))
print(lst2)

['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 number in lst1:
    lst2.append(number **  2)
print(lst1)
print(lst2)

[3, 7, 6, 8, 9, 11, 15, 25]
[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, 0]
lst2=[]
lst3=[]
#Type your answer here.
for number in lst1:
    if number >= 0:
        lst2.append(number)
    else:
        lst3.append(number)

print(lst2)
print(lst3)
print(lst1)

[111, 32, 9, 85, 0]
[-9, -45, -17, -10]
[111, 32, -9, -45, -17, 9, 85, -10, 0]

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, ["hello", "goodbye"], {"goodbye", "hello"}]
lst2=[]
#Type your answer here.
for item in lst1:
    itemtype = type(item)
    lst2.append(item)
    lst2.append(itemtype)
print(lst2)

[3.14, <class 'float'>, 66, <class 'int'>, 'Teddy Bear', <class 'str'>, True, <class 'bool'>, ['hello', 'goodbye'], <class 'list'>, {'hello', 'goodbye'}, <class 'set'>]
