python - Generate random data with lat-long -

i trying generate random data range of specific latitude , longitude. code below executes no errors , generates output not expecting.

program:

import random import sys import math  latitude = 19.99 longitude = 73.78 output_file = 'filename'  def generate_random_data():     open(output_file, 'w') output:         hex1 = '%012x' % random.randint(0,100)         flt = float(random.randint(0,100))         latitude = math.acos(random.random() * 2 - 1)         longitude = random.random() * math.pi * 2          output.write('%s %.1f %.6f %.6f \n' % (hex1.lower(), flt, longitude, latitude))  if __name__ == '__main__':     generate_random_data() 

the above code runs gives 1 row (which indentation problem) not give me random lat & long in required geo location mentioned above.

output generated:

000000000020 95.0 3.929691 1.749931

output expected: 000000000020 95.0 19.999691 73.799931

and generates one row trying have million rows

i think trying do. understand writing file; took off here sake of example.

import random import sys import math  latitude = 19.99 longitude = 73.78  def generate_random_data(lat, lon, num_rows):     _ in xrange(num_rows):         hex1 = '%012x' % random.randrange(16**12) # 12 char random string         flt = float(random.randint(0,100))         dec_lat = random.random()/100         dec_lon = random.random()/100         print '%s %.1f %.6f %.6f \n' % (hex1.lower(), flt, lon+dec_lon, lat+dec_lat)  generate_random_data(latitude, longitude, 5) 

prints:

31d831302b7f 99.0 73.789561 19.997404  c6ef41c70ebb 0.0 73.780732 19.994279  4bc2df5388e3 77.0 73.785531 19.994191  e7648f673475 40.0 73.786610 19.993679  a11502c744a6 32.0 73.784650 19.997702  

edit: function including writing file following

import random import sys import math  latitude = 19.99 longitude = 73.78 file_n = 'random_lat_lon.txt'  def generate_random_data(lat, lon, num_rows, file_name):     open(file_name, 'w') output:         _ in xrange(num_rows):             hex1 = '%012x' % random.randrange(16**12)                             flt = float(random.randint(0,100))             dec_lat = random.random()/100             dec_lon = random.random()/100             output.write('%s %.1f %.6f %.6f \n' % (hex1.lower(), flt, lon+dec_lon, lat+dec_lat))  generate_random_data(latitude, longitude, 5, file_n) 

which generates data posted above edit file named 'random_lat_lon.txt'.
