How to read text file as list of floats? [duplicate]-CodePudding

This seems like a simple question, but couldn't find it on the Stack community. I have a dataset like the one below in a text file. I would like to read it in as a list with each value as a float. Currently the output is very odd from the simple list needed (also below).

data.txt:

[1130.1271455966723, 1363.3947962724474, 784.433380329118, 847.2140341725295, 803.0276763894814,..]

Code attempted:

my_file = open(r"data.txt", "r")
content = my_file.read()
content_list = content.split(",")
my_file.close()

The output is odd. The values are string and list inside of list and added spaces:

Current result:

['[1130.1271455966723',
 ' 1363.3947962724474',
 ' 784.433380329118',
 ' 847.2140341725295',
 ' 803.0276763894814',
 ' 913.7751118925291',
 ' 1055.3775618432019',...]']

I also tried the approach here (How to convert string representation of list to a list?) with the following code but produced an error:

import ast
x = ast.literal_eval(result)
raise ValueError('malformed node or string: '   repr(node))
ValueError: malformed node or string: ['[1130.1271455966723', '1363.3947962724474', ' 784.433380329118', ' 847.2140341725295', ' 803.0276763894814',...]']

Ideal result:

list = [1130.1271455966723, 1363.3947962724474, 784.433380329118, 847.2140341725295, 803.0276763894814]

CodePudding user response：

Your data is valid JSON, so just use the corresponding module that will take care of all the parsing for you:

import json

with open("data.txt") as f:
    data = json.load(f)

print(data)

Output:

[1130.1271455966723, 1363.3947962724474, 784.433380329118, 847.2140341725295, 803.0276763894814]
