The best way to convert python list items from string to number
Question:
I have a list like this:
id=['"1',
'"1',
'"2',
'"2',
'"1',
'"1',
'"2',
'"2'
]
what is the best way to convert all the item to numbers, now they are strings.Out put should like:
id=[1,
1,
2,
2,
...
2]
Answers:
You can try:
numbers = [int(s.replace('"', '')) for s in id]
print(numbers)
# [1, 1, 2, 2, 1, 1, 2, 2]
and please don’t use id as a variable name, as it’s already a name used by python
You can also make a loop to convert every item into an integer
for i in range(len(id)):
id[i] = int(id[i])
