How would I create a list of rounded numbers on python?-CodePudding

How would I round these float values in the list below to create a list of float values rounded to the nearest whole number using list comprehension? aList = ['3.32', '1.08', '4.23]

and have the new list be [3.0, 1.0, 4.0]

CodePudding user response：

It is pretty easy just use the built function int().

aList = [3.32, 1.08, 4.23]
newList = []
for num in aList:
    newList.append(int(num))
print(newList)

Note: those elements in your list are not float numbers but strings.

I'm assuming aList is supposed to be ['3.32', '1.08', '4.23'] (missing quote at the end).

You can convert the strings into floats, then round them with 0 digits of precision, like this:

newList = [round(float(n), 0) for n in aList]

result:

[3.0, 1.0, 4.0]

input_list = [3.32, 1.08, 4.23]
output_list = [round(x) for x in input_list]
