>>>importsend2trash>>>baconFile=open('bacon.txt','a')# creates the file>>>baconFile.write('Bacon is not a vegetable.')25>>>baconFile.close()>>>send2trash.send2trash('bacon.txt') 一般来说,你应该总是使用send2trash.send2trash()函数来删除文件和文件夹。但是,虽然将文件发送到回收站可以...
File"<stdin>", line1,in<module> TypeError: unsupported operandtype(s)for/:'str'and'str' Python 从左到右计算/操作符,并计算出一个Path对象,因此最左边的第一个或第二个值必须是一个Path对象,整个表达式才能计算出一个Path对象。下面是/操作符和一个Path对象如何计算出最终的Path对象。 如果您看到前面显...

一、写文件write() 打开文件 open(); name = "巴啦啦-小魔仙" # 定义一个变量name fileobj = open('school.txt', 'w') #使用open()函数打开一个原本不存在的的文件, #‘w’覆盖原文件内容,将这个函数传递给变量fileobj fileobj.write(name) # 再用write()方法,将变量name写入到fileobj ...
a= open('text.txt',"w") a.write("this is how you create a new text file") a.close() 可以从创建一个make-text-file()函数开始,告诉python开打一个名为test.txt的文件。由于python找不到该文件,就会自己创建,注意:如果该文件存在,python会删除它并创建一个新文件,后面将需欸写如何在创建一个文件...
