I have a list of objects appended from a mysql database and contain spaces. I wish to remove the spaces such as below, but the code im using doesnt work?
hello = ['999 ',' 666 ']
k = 
for i in hello:
Strings in Python are immutable (meaning that their data cannot be modified) so the replace method doesn't modify the string - it returns a new string. You could fix your code as follows:
for i in hello: j = i.replace(' ','') k.append(j)
However a better way to achieve your aim is to use a list comprehension. For example the following code removes leading and trailing spaces from every string in the list using
hello = [x.strip(' ') for x in hello]
