String Manipulations¶

strip (remove whitespace or other characters)

>>> value = '  25.3  '
>>> value
'  25.3  '
>>> value.strip()
'25.3'
>>> quoted = '"this"'
>>> quoted
'"this"'
>>> quoted.strip('"')
'this'

split, join

>>> row = 'Silver Deer,69,-0.115,0.993,-0.12,25,violet'
>>> components = row.split( ',' )
>>> components
['Silver Deer', '69', '-0.115', '0.993', '-0.12', '25', 'violet']
>>> print("\n".join( components ))
Silver Deer
69
-0.115
0.993
-0.12
25
violet
>>> not_all_strings = [ 'Silver Goat', 45, -.333, .75, .08, 5, 'violet' ]
>>> "\n".join( not_all_strings )
Traceback (most recent call last):

format

>>> count = 53
>>> mean = 37.036
>>> label = 'DMX Score'
>>> '{0},{1},{2}'.format( label, count, mean )
'DMX Score,53,37.036'
>>> '{0!r} for {1} items {2:0.2f}'.format( label, count, mean )
"'DMX Score' for 53 items 37.04"
