SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in position 100-101: truncated \UXXXXXXXX escape 是一个Unicode编码错误。它通常发生在字符串中包含了无效的Unicode转义序列时。这个错误的原因可能是因为在字符串中使用了不正确的转义字符,或者转义字符的格式不正确。
为了解决这个问题,你可以尝试以下几种方法:
1. 使用原始字符串(Raw String):在字符串前面加上字母r,表示这是一个原始字符串,不会对其中的转义字符进行处理。例如:
```python
path = r"C:\Users\Administrator\Desktop\./TEST.xlsx"
```
2. 双斜杠转义:将字符串中的单个反斜杠替换为双斜杠。例如:
```python
path = "C:\\Users\\Administrator\\Desktop\\./TEST.xlsx"
```
3. 使用正斜杠:将字符串中的反斜杠替换为正斜杠。例如:
```python
path = "C:/Users/Administrator/Desktop/./TEST.xlsx"
```
请注意,以上方法中的任何一种都可以解决这个问题,你可以根据自己的需求选择其中一种方法来修复这个错误。

这个错误是由于在字符串中使用了不正确的转义字符引起的。在Python中,反斜杠(\)被用作转义字符,用于表示特殊字符。当字符串中的反斜杠后面跟着一个无效的转义序列时,就会出现这个错误。
为了解决这个问题,你可以使用原始字符串(raw string)来避免转义字符的影响。原始字符串使用前缀r或R来表示,它会将反斜杠视为普通字符,而不是转义字符。
下面是一个示例,演示如何使用原始字符串来避免这个错误:
```python
wb = xlrd.open_workbook(r"C:\Users\Administrator\Desktop\./TEST.xlsx")
```
在这个示例中,字符串前面的r表示这是一个原始字符串,所以反斜杠不会被视为转义字符。
SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in position 2-3: truncated \UXXXXXXXX escape
This error occurs when a string contains a Unicode escape sequence that is not valid. The escape sequence starts with a backslash (\) followed by one or more characters that specify the Unicode code point.
For example, "\U0001F600" is a valid Unicode escape sequence that represents the "grinning face" emoji. However, if the sequence is truncated, i.e., if the number of characters after the backslash is not sufficient to represent a valid Unicode code point, a SyntaxError with the message "unicodeescape' codec can't decode bytes" is raised.
To fix this error, you need to make sure that all Unicode escape sequences in your strings are valid and complete. Check the string that caused the error and make sure that all backslashes are followed by the correct number of characters to represent a valid Unicode code point. If necessary, use an online Unicode converter to get the correct sequence for the character you want to include in your string.
