我们如何在数据框中的列中的字符串周围添加引号

Question

I have a field named 'location'; it looks like this.

3200 PROVIDENCE DRIVE ANCHORAGE 99508
2500 SOUTH WOODWORTH LOOP PALMER 99645
3260 HOSPITAL DR JUNEAU 99801
1650 COWLES STREET FAIRBANKS 99701
2801 DEBARR ROAD ANCHORAGE 99508

I am trying to add double quotes around the string, so it looks like this.

"3200 PROVIDENCE DRIVE ANCHORAGE 99508"
"2500 SOUTH WOODWORTH LOOP PALMER 99645"
"3260 HOSPITAL DR JUNEAU 99801"
"1650 COWLES STREET FAIRBANKS 99701"
"2801 DEBARR ROAD ANCHORAGE 99508" 

I tried this (it does something very weird):

for col in results:
    results['location'] =  results['location'].apply(lambda x: """ + str(x) + """)

I also tried this (it adds way too many quotes):

for col in results:
    results['location'] = '"' + results['location'] + '"'

Thoughts?

Answer 1

@ASH, try this:

['"'+str(x)+'"' for x in words]

Output:

['"3200 PROVIDENCE DRIVE ANCHORAGE 99508"',
 '"2500 SOUTH WOODWORTH LOOP PALMER 99645"',
 '"3260 HOSPITAL DR JUNEAU 99801"',
 '"1650 COWLES STREET FAIRBANKS 99701"',
 '"2801 DEBARR ROAD ANCHORAGE 99508"']

Answer 2

You could use an f-string in the lamba.

for col in results:
    results['location'] = results['location'].apply(lambda x: f'"{x}"')
