CSV文件可以。不能转换为浮点型

import csv

def convert_to_float(value):
    try:
        return float(value)
    except ValueError:
        return None  # 或者其他默认值

with open('data.csv', 'r') as file:
    reader = csv.reader(file)
    for row in reader:
        float_row = [convert_to_float(item) for item in row]
        print(float_row)

import csv

def clean_value(value):
    return value.strip()

with open('data.csv', 'r') as file:
    reader = csv.reader(file)
    for row in reader:
        cleaned_row = [clean_value(item) for item in row]
        float_row = [convert_to_float(item) for item in cleaned_row]
        print(float_row)

import csv

with open('data.csv', 'r', encoding='utf-8') as file:  # 根据实际情况选择合适的编码
    reader = csv.reader(file)
    for row in reader:
        float_row = [convert_to_float(item) for item in row]
        print(float_row)
