Change in Python 3.3 with the treatment of sys.argv

Show all headers | View raw

Below is an extract from some code to run on Python 2.7.3, 3.2.3 and 
3.3.0 to compare speeds, both between versions and machines:

if __name__ == '__main__':
     # Text string for initial test - Modify for your own machine or
     # delete it and and answer the input statement with your own machine
     # characteristics.
     sys.argv[1:]= ('Intel Pentium D CPU 3.0GHz 1.99 GB of RAM 221GB 
Disk Free space', )
     main()


def main():
     if len(sys.argv) > 1:
         idMachine= ' '.join(sys.argv[1:])
     ...
     oFile= open('FP' + now + '.log', 'w')
     oFile.writelines(idM + '\n' + sys.version + '\n')

For 2.7, the result is:
Intel_Pentium_D_CPU_3.0GHz_1.99_GB_of_RAM_221GB_Disk_Free_space
2.7.3 (default, Apr 10 2012, 23:31:26) [MSC v.1500 32 bit (Intel)]

for 3.2, the result is:
Intel_Pentium_D_CPU_3.0GHz_1.99_GB_of_RAM_221GB_Disk_Free_space
3.2.3 (default, Apr 11 2012, 07:15:24) [MSC v.1500 32 bit (Intel)]

For 3.3, the result is:
I_n_t_e_l___P_e_n_t_i_u_m___D___C_P_U___3_._0_G_H_z___1_._9_9___G_B___o_f___R_A_M___2_2_1_G_B___D_i_s_k___F_r_e_e___s_p_a_c_e
3.3.0 (v3.3.0:bd8afb90ebf2, Sep 29 2012, 10:55:48) [MSC v.1600 32 bit 
(Intel)]

The full test result, for random matrices of increasing order is 
available here(http://web.ncf.ca/cjw/FP%20Summary%20over%20273-323-330.txt)
