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??
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)) 
write method, you need to write str.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
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!
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 .
output.txt. If you want to use the user's input as the file name, you'll have to pass something likeoutput + '.txt'to theopenfunction.
