Write Rows In Columns In File In Python

I have sentences,in a form of a string, that look like this : First sentence hund barked 4.51141770734e-07 bit 0.0673737226603 dog

Solution 1:

Suppose you have two lists of lines, lines1 and lines2. If you have a string with multiple newlines, you can make a list of lines by calling .split('\n').

Then, you can format them into parallel columns with string formatting:

lines = ['{:<40}{:<40}'.format(s1, s2) for s1, s2 in zip(lines1, lines2)]

Example:

a = '''            hund                    
barked      4.51141770734e-07
bit         0.0673737226603
dog         0.932625826198'''.split('\n')
b = '''            hyi                     
biid        6.12323423324e-07
bok         0.0643253
dyfs        0.514586321'''.split('\n')
lines = ['{0:<40}{1:<40}'.format(s1, s2) for s1, s2 inzip(a,b)]
print'\n'.join(lines)

Output:

            hund                                    hyi                         
barked      4.51141770734e-07           biid        6.12323423324e-07           
bit         0.0673737226603             bok         0.0643253                   
dog         0.932625826198              dyfs        0.514586321                 

Solution 2:

If it's string formatting you're after, you might want to look as str.ljust to make a string a certain length.
