如何将输出保存为.txt文件？

Question

I want to save the output as a text file on my system. The name of the output file should get from the user in command prompt.

   output = input("Enter a name for output file:")    

   my_file = open('/output.txt', "w") 

    for i in range(1, 10):
       my_file.write(i)

Is this correct way of doing??

Answer 1

Do like this

output = raw_input("Enter a name for output file:")    
my_file = open(output + '.txt', "w") 
for i in range(1, 10):
    my_file.write(str(i))

Answer 2

You can do the following:

import os

# you can use input() if it's python 3
output = raw_input("Enter a name for output file:")

with open("{}\{}.txt".format(os.path.dirname(os.path.abspath(__file__)), output), "w") as my_file:
    for i in range(1, 10):
        my_file.write("".format(i))

At this example we are using the local path by using os.path.dirname(os.path.abspath(__file__)) we will get the current path and we will add it output.txt

1. To read more about abspath() look here

2. To read more about with look here

3. write method in you case will raise a TypeError since i needs to be a string

Answer 3

So couple of changes I made. You need to do something like:

    output + '.txt'

to use the variable output as the file name.

Apart from that, you need to convert the integer i to a string by calling the str() function:

    str(i)

becuase the write function only takes strings as input.

Here is the code all together:

    output = raw_input("Enter a name for output file: ")    

    my_file = open(output + '.txt', 'wb') 

    for i in range(1, 10):
        my_file.write(str(i))

    my_file.close()

Hope this helps!

Answer 4

You can do it in one line so you will have your txt file in your .py file path:

 my_file=open('{}.txt'.format(input('enter your name:')),'w')
 for i in range(1, 10):
    my_file.write(str(i))
 my_file.close()

Note: if you are using python 2.x use raw_input() instead of input .
