D:\python\Lib\site-packages\pandas\io\parsers\readers.py:948 是 pandas 库中的一个文件路径,它是用于读取 CSV 文件的模块。在这个文件中,read_csv 函数位于第 948 行。read_csv 函数是 pandas 提供的一个非常常用的函数,用于从 CSV 文件中读取数据并创建一个 DataFrame 对象。
read_csv 函数的主要参数包括文件路径、分隔符、列名等。它可以根据指定的参数读取 CSV 文件,并将数据解析为一个二维表格形式的数据结构。这个函数还支持处理缺失值、日期解析、数据类型推断等功能,使得数据的读取和处理更加方便和灵活。

这个错误是由于 Pandas 读取 CSV 文件时默认使用 `UTF-8` 编码,但是你的 CSV 文件使用的编码格式可能与此不同。你可以尝试指定正确的编码格式,例如:
```
data = pd.read_csv("C:/Users/93037/Desktop/credit_card.csv", encoding='gbk')
```
其中 `gbk` 是中文编码格式之一,你可以根据实际情况选择正确的编码格式。如果仍然存在问题,请检查 CSV 文件的编码格式是否正确,并尝试使用其他编码格式解决问题。

这个错误提示是Unicode解码错误,可能是因为文件编码不是UTF-8格式导致的。建议尝试更改读取文件时使用的编码方式,例如使用GBK或者GB2312编码方式打开文件。可以使用以下代码:
```python
import pandas as pd
data = pd.read_csv('data.csv', encoding='GBK')
```
如果还是无法解决问题,可能需要检查一下data.csv文件本身是否存在编码问题。
