Python function to write tables with user-defined columns number to a text file:



def print_table(list, cols, file_name):

file = open(file_name,"w")
length = len(list)
i = 1
list.insert(0,-999.0)

while i <= length:
file.write("%7.1f " % float(list[i]))
if i % cols == 0: file.write("\n")
i = i + 1

file.write("\n")
file.close()



Example usage:



>> print_table(range(34),7,"data.dat")
