Python learning notes – error: Please select a valid Python interpreter

Question

The following error occurs when running: Please select a valid Python interpreter
the English meaning of this sentence: “please select a valid Python interpreter”

In fact, it’s because you just downloaded pychar, and you haven’t done its basic configuration yet. The error is normal ~

Solution:

First, Download python (again)

Open the DOS command line window,

ah, with ~

Then, the parser selects the problem, opens settings (Ctrl + Alt + s) or file & gt; settings, and opens the configuration box, as shown in the following figure:

Just follow the steps:

The results are shown in the figure below:

Then you can!

[Solved] AttributeError: ‘DataFrame‘ object has no attribute ‘tolist‘

 

solve the problem

return object.__getattribute__(self, name)
AttributeError: ‘DataFrame’ object has no attribute ‘tolist’

Solution ideas

Property error: ‘dataframe’ object does not have property ‘tolist’

Solution:

Remember that DataFrame does not have a tolist() method, but series.Series has a tolist() method, so it needs to be modified

take

import pandas as pd

#Read xls file
file_path='data/test1226.xls'
data_frame_xls=pd.read_excel(file_path)
data_df01 = data_frame_xls[['age']]
print(type(data_df01))
print(res)

Change to

import pandas as pd

#Read xls file
file_path='data/test1226.xls'
data_frame_xls=pd.read_excel(file_path)
data_df01 = data_frame_xls[['age']]
print(type(data_df01))

data_df01 = data_frame_xls['age']
print(type(data_df01 ))
res = data_df01 .tolist()
print(res)

Ha ha, it’s done!

django.core.exceptions.ImproperlyConfigured: Error loading MySQLdb module.
Did you install mysqlclient?

One of the reasons for this error when starting the Django project is:

Because pymysql is not installed or not configured,

Pymysql is not installed. It needs to be built into the environment and executed

import pymysql
pymysql.install_as_MySQLdb()

Done!

NameError: name ‘xrange‘ is not defined [How to Solve]

The reason is that my Python version is Python 3.8, while the xrange() function is in Python 2.0 For a function in X, in Python 3, the implementation of range () is the same as that of xrange (), so there is no special xrange (). Therefore, when this problem is encountered, there are two methods to solve it.

Solution:

1: if you want to run the program in Python 3, change all xrange() functions to range().

2: put the program with this problem in Python 2.X version of the environment can be run
