Question

我只是从python开始，并针对此错误。谁会知道为什么以及是否要将数据保存为整数或如何做到这一点？

Traceback (most recent call last):
  File "C:\Users\Gabriela Lammoglia\AppData\Local\Programs\Python\Python37-32\open.py", line 34, in <module>
    latt2=mult*lattice

代码：

from csv import reader
from collections import defaultdict
from ast import literal_eval
from pprint import pprint

data = defaultdict(list)
with open('crystal.csv') as f:
    csv_reader = reader(f)

    current_header = None
    for line in csv_reader:

        # We found a header
        if len(line) == 1 and all(item.isalpha() or item.isspace() for item in line[0]):
            current_header = line[0]

        # Otherwise normal line with ints and floats
        else:
            data[current_header].append(list(map(literal_eval, line)))

pprint(data)

mult=data['multiplicty']
lattice=data['lattice parameters']
occup=data['occupancy']
sites=data['atom sites']

print(mult)
print(lattice)
print(occup)
print(sites)

import numpy as np
latt2=mult*lattice

Answer 1

latt2=int(mult)*lattice

您需要将多值设为整数。现在，您尝试使用多个字符串和列表，这是个坏主意。

错误：TypeError：无法将序列乘以'list'类型的非整数
