I have a list that contains "n" elements of type str .
However, I need to get these elements to be integers. How can I do this?
For example, I have this list here:
trechos = conteudo[2:len(conteudo)]
It turns out that I can not just force it like this:
int(conteudo[2:len(conteudo)])
Because python gives error. How can I make each value integer? And then pass those integer values to a new list?
items = ['1', '2', '-10', 'A', '1234567890']
for item in items:
print('{} type: {}'.format(item, type(item)))
int_items = [int(value) for value in items if value.lstrip('-').isdigit()]
for item in int_items:
print('{} type: {}'.format(item, type(item)))
1 type: <class 'str'>
2 type: <class 'str'>
-10 type: <class 'str'>
A type: <class 'str'>
1234567890 type: <class 'str'>
1 type: <class 'int'>
2 type: <class 'int'>
-10 type: <class 'int'>
1234567890 type: <class 'int'>
