I have this list
['456-789-154','741-562-785','457-154-129']
I want to convert it to int list like this:
[456,789,154,741,562,785,457,154,129]
Please help!!
I tried:
list = [item.replace("-",",") for item in list)
list = [item.replace("'","") for item in list)
But I don't know why the second line is not working.
Use a double list comprehension:
l = ['456-789-154','741-562-785','457-154-129']
num_list = [int(y) for x in l for y in x.split("-")]
print(num_list) # [456, 789, 154, 741, 562, 785, 457, 154, 129]
You can use the following approach
my_list = ['456-789-154','741-562-785','457-154-129']
new_list = []
sub_list = []
for item in my_list:
sub_list = item.split("-")
for item in sub_list:
new_list.append(int(item))
print(new_list)
Output
[456, 789, 154, 741, 562, 785, 457, 154, 129]
Use re.findall to return all stretches of digits, then flatten the list of lists and convert to int:
import re
strs = ['456-789-154','741-562-785','457-154-129']
nums = [int(num) for sublist in (re.findall(r'\d+', s) for s in strs) for num in sublist]
print(nums)
# [456, 789, 154, 741, 562, 785, 457, 154, 129]
