I have the list below, which contains strings and integers. How do I make a string of them? Tried to use
''.join(l)
but it does't work, because there are integers on the list(specifically, L[1] is an integer, and the others are all strings.). Can you help?
L=['1', 9, ':', '0', '5', ':', '4', '5']
#expected "19:05:45"
You can convert each number in the list into a string with a for loop or list comprehension. Like so:
l = ['1', 9, ':', '0', '5', ':', '4', '5']
''.join([str(x) for x in l])
'19:05:45'
Generators are perfect in this case:
>>> l = ['1', 9, ':', '0', '5', ':', '4', '5']
>>> ''.join(str(x) for x in l)
'19:05:45'
This looks the same as a list comprehension but does not require the creation of another list instance.
Just map all the elements to string before joining.
>>> ''.join(map(str,['1', 9, ':', '0', '5', ':', '4', '5']))
'19:05:45'
You can do it in a for loop
list_str = ''
for i in l:
list_str += str(i)
Or a with a list comprehension
list_str = ''.join([str(i) for i in l])
