file1 = open('E:/hello/hello.txt') file2= open('output.txt','w') #w是可写的文件whileTrue: line=file1.readline() #readline()是读取一行 # 这里可以进行逻辑处理 file2.write('"'+line[:]+'"'+",")ifnot line : #如果行读取完成,就直接跳出循环break#记住文件处理完成关闭文件是一个号习...

End your function with a return statement if the function should output something. Without the return statement, your function will return an object None. Of course, your functions will get more complex as you go along: you can add for loops, flow control, … and more to it to make it ...
f.write("This is line %d\r\n" % (i+1)) We have afor loopthat runs over a range of 10 numbers. Using thewritefunction to enter data into the file. The output we want to iterate in the file is “this is line number”, which we declare with Python write file function and then ...
