numy使用
调用numy函数，想把数据以矩阵形式读出来，数据之间的逗号用中文会报错，英文逗号不会，这是为什么？#numpy 读写以矩阵形式
import numpy
a=numpy.genfromtxt("C:\\Users\\lzj\\Desktop\\text.txt",delimiter=",",dtype=str)
print(a)
报错如下：
ValueError Traceback (most recent call last)
<ipython-input-99-0853a2d82c3b> in <module>()
1 #numpy 读写以矩阵形式
2 import numpy
----> 3 a=numpy.genfromtxt("C:\\Users\\lzj\\Desktop\\text.txt",delimiter=",",dtype=str)
4 print(a)

import numpy
a = numpy.genfromtxt("test.txt", delimiter="，", dtype=str, encoding='utf-8') # 以中文逗号分隔，得修改默认encoding。
print(a)
txt,csv 啥的一般默认是英文的逗号进行分隔
