How to print list from input with specific items

Question

How to print list with from input with specific items? For example with names which ends with x. I've got this code

while True:
    name = input("Enter your name: ")
    if name == "":
        break
    list = []
    namex = name.endswith("x")
    if name == namex:
        list.append(name)
    print (list)

but when i try to print list it gives me nothing:

>>> Enter your name: alex
    Enter your name: james
    Enter your name: abcx
    Enter your name: 
>>>

Answer 1

Your issue is that namex is a boolean , not a string .

>>> 'abc'.endswith("x")
False
>>> 'abcx'.endswith("x")
True

This means that any equality comparison between a string and a boolean will return false. You want to trigger the "if" statement if the statement ends with "x", or:

names = []
while True:
    name = input("Enter your name: ")
    if name == "":
        break
    namex = name.endswith("x")
    # namex is a boolean type, which if it is True, will trigger an if statement
    if namex:
        names.append(name)
print(names)

Answer 2

namex = name.endswith("x")
if name == namex:

Does not do what you think it does. name.endswith("x") returns True or False . Should be

if name.endswith("x"):

instead.

names = []
while True:
    name = input("Enter your name: ")
    if name == "":
        break
    if name.endswith("x"):
        names.append(name)
print (names)

List comprehension iter version:

>>> [name for name in iter(input, '') if name.endswith('x')]
dsf
sdfdsf
dsffdx
sx

['dsffdx', 'sx']

Answer 3

Here, I am storing all the names ending with 'x' in namex_list instead of using the list (also a built-in variable) variable you used before.

Also, i am assigning namex_list as an empty list before the while condition and printing the namex_list at the end outside of while .

namex_list = []
while True:
    name = input("Enter your name: ")
    if name == "":
        break     
    if name.endswith("x"):
        namex_list.append(name)
print (namex_list)

Also, name == namex does not check what you are trying to achieve because of the comparison between string values and boolean values.

For example:

>>> name1 = 'abc'
>>> name2 = 'abcx'
>>> namex1 = name1.endswith('x')
>>> namex2 = name2.endswith('x')

>>> namex1
False
>>> namex2
True

>>> name1 == namex1    
False
>>> name2 == namex2
False

You should use an if instead to achieve what you are trying to achieve in your code above:

if name.endswith("x"):
