I have a list of strings but I want to make single double quotes before and after each string. If I have the list
words = ['abc', 'acd', 'edf']
I want to change it to:
words = [''abc'', ''cdf'', ''edf'']
How can I do it with list comprehension or other method? I want two sets of single quotation marks. I want this to pass to redshift to unload the query result to s3.https://docs.aws.amazon.com/redshift/latest/dg/r_UNLOAD.html
Try like this:
words = ['abc', 'acd', 'edf']
words = ['\'\'{}\'\''.format(x) for x in words]
print(words)
well python syntax won't allow
words = [''abc'', ''cdf'', ''edf'']
we have to use escape characters \\"
or \\'
; in your case since you want two: \\"\\"
or \\'\\'
words = ['abc', 'cdf', 'edf']
words = [f"\'\'{word}\'\'" for word in words]
now the following is stored in words
:
["''abc''", "''cdf''", "''edf''"]
you can also use f strings wrapped with double quotations and normally add single quotations (im not saying this is proper but it does work)
words = [f"''{word}''" for word in words]
["''abc''", "''cdf''", "''edf''"]
Maybe I am misunderstanding you but cant you just use double quotes to signify the string notation and use the single quotes for the string content?, then just concatenate with +
:
words = ['abc', 'acd', 'edf']
new_list = ["''"+item+"''" for item in words]
