Issue

How would I convert the following string to an array with python (this string could have an indefinite number of items)?

'["Foo","Bar","Baz","Woo"]'

This is definitely a string representation as well. type() gave:

<class 'str'>

Update:

Got it.

interestedin = request.POST.get('interestedIn')[1:-1].split(',')

interested = []

for element in interestedin:
    interested.append(element[1:-1])

Where request.POST.get('interestedIn') gave the '["Foo","Bar","Baz","Woo"]' string list “thing”.

Solution

Dealing with string ‘[“Foo”,”Bar”,”Baz”,”Woo”]’

str = '["Foo","Bar","Baz","Woo"]'
str1 = str.replace(']','').replace('[','')
l = str1.replace('"','').split(",")
print l # ['Foo', 'Bar', 'Baz', 'Woo'] A list

If you mean using python array module, then you could do like this:

import array as ar
x=ar.array('c')  #char array
for i in ['Foo', 'Bar', 'Baz', 'Woo']: x.extend(ar.array('c',i))
print x  #array('c', 'FooBarBazWoo')

It will be much simpler if you consider using numpy though:

import numpy as np
y=np.array(['Foo', 'Bar', 'Baz', 'Woo'])
print y #  ['Foo' 'Bar' 'Baz' 'Woo']
