Need to write contents of file to a .txt

[Deathwing]

Hello,

I'm fairly new to python and have only been playing around with it for one week actually. It's my first attempt at programming and I'm trying to generate some random floats and then have the results of this random generation be filled into a .txt file. So far I have only been able to generate random intergers and create a blank .txt. Can anyone help ? How do I get my ints to turn to floats I have tried using the "float" datatype infront of my numbers but that does not work. Also, how after having generated the random numbers do I get them to populate the .txt file that is created.

Thanks so very much

Here is my code thus far:

# Random number generator
# This script generates random numbers
# The script then writes the result to a text file


text_file = open("points.tx t", "w")
#text_file.writ e(i)

import random

for numbers in range( 1, 201 ):
print "%5d" % ( random.randrang e( 1, 201 ) ),

if numbers % 6 == 0:
print


#text_file.writ elines(numbers)

text_file.close ()

raw_input("\n\n Press the enter key to exit.")

Maybe you can modify this to meet your requirements:

import random
 
# generate 20 random numbers and write to a text file
 
f = open(r'path\dir\file_name', 'w')
for i in range(20):
    f.write('%.8f\n' % (random.random()))
 
f.close()

Here is another way:

import random
 
f = open(r'path\dir\file_name', 'w')
f.writelines(['%.8f\n' % (random.random()) for _ in range(20)])
f.close()

Thanks bvdet, I'll take a look at it I hope I can modify it, it looks very interesting you have taught me something new todya great! :"D.

Sincerely,

eg

python -c "import random; print '\n'.join([str(random.randint(1,201)) for i in range(20)])" > file

eg

python -c "import random; print '\n'.join([str(random.randint(1,201)) for i in range(20)])" > file      
 

could you explain? I'm sorry I don't understand

f.close()

Hey bvdet thanks for the tip I have managed to adjust it somewhat but I need to figure out how to get the output/data in to x and y columns here is my modified code. Hope you can help.

#text_file.write(i)
 
 
 
for i in range( 1, 601 ):
 
 
   f.write( "%5f\n" % ( random.randrange( 1, 601 ) )),
 
  #if numbers % 6 == 0:  
     #print
 
 
#text_file.writelines(numbers)
 
f.close()

What do you mean by "get the output/data in to x and y columns"?. Instead of each number on a separate line, do you want the numbers in pairs?

hi there and yep an x and y column you are correct I do want numbers in pairs. :)

Please read "REPLY GUIDELINES" so that you know how to use CODE tags.
Then start using them. It's a real pain for others to try and see the structure of your code without them.

Thank you very much.
