使用python读取屏幕上的文本

如何解决使用python读取屏幕上的文本

如何从文本文件中获取文本并将其保存为python中的变量？我尝试将其保存为图像，然后使用 PyTesseract.image_to_string() 但它似乎不起作用

解决方法

可以试试python的pickle模块：pickle documentation pickle example RealPython

我正在发布一个示例，不确定它是您要查找的内容，我的意图

来自'变量是存储数据值的容器'的意思：

#!/usr/bin/env python3
# -*- coding: utf-8 -*-



import pickle

# reads your textfile.txt and stores as 'variable'

with  open("textfile.txt","r") as textfile: 
            variable=textfile.read()
           
print('\ntextfile.txt content: ',variable)
                
textfile.close()

#dumps the variable to a binary pickle serialized file

with open("variablefile.var",'wb') as variablefile:
    pickle.dump(variable,variablefile)

#loads a new variable from the binary pickle serialized file

with open("variablefile.var",'rb') as variablefile:
    variableloaded = pickle.load(variablefile)
    
    
print('variable loaded from file',variableloaded)

print('\nvariable loaded type from file',type(variableloaded))
    

或者您可以将数据存储在字典中并以 JSON 格式保存（JSON 代表 JavaScript Object Notation。这种格式是一种以键值排列存储数据的流行方法，以便以后可以轻松解析。）{ {3}}

#!/usr/bin/env python3
# -*- coding: utf-8 -*-



import json

# create empty dictionary

variables_dict = {}


# reads your textfile.txt and stores as 'textfile.txt' inside the dictionary

with  open("textfile.txt","r") as textfile: 
            variables_dict["text.file.txt"]= textfile.read()
           
print('\nvariables_dict : ',variables_dict)
                
textfile.close()

#save the dictionary as a json file 'variables.json'

with open('variables.json','w') as variablessaved:
    json.dump(variables_dict,variablessaved)
    

#read the dictionary as a json file 'variables.json'

    
with open('variables.json','r') as variablesloaded:
    loaded_dict = json.load(variablesloaded)
    


print('\nloaded dictionary : ',loaded_dict)

同样，我不确定您在寻找什么。
