解决’tuple’ object is not callable的报错-python变量命名错误
This [error](https://wenku.csdn.net/doc/6401acf5cce7214c316edc34?spm=1055.2569.3001.10083) occurs when you try to call a Range[index](https://wenku.csdn.net/doc/89jocm11r2?spm=1055.2569.3001.10083) object as a function, which is not [allow](https://wenku.csdn.net/doc/64531692fcc539136803e951?spm=1055.2569.3001.10083)ed in [python](https://wenku.csdn.net/doc/6412b46ebe7fbd1778d3f92a?spm=1055.2569.3001.10083).
For example, consider the following code snippet:
import pandas as pd
df = pd.[dataframe](https://wenku.csdn.net/doc/64534c09ea0840391e779430?spm=1055.2569.3001.10083)({'A': [1, 2, 3], 'B': [4, 5, 6]})
idx = pd.RangeIndex(start=0, stop=3)
idx()
Here, we create a RangeIndex object `idx` with start and stop values, and then try to call it as a function. This will result in the error message: "'RangeIndex' object is not callable".
To fix this error, remove the parentheses after the RangeIndex object:
import pandas as pd
df = pd.DataFrame({'A': [1, 2, 3], 'B': [4, 5, 6]})
idx = pd.RangeIndex(start=0, stop=3)
Now, the code will work correctly and return the RangeIndex object.
