Want get value of other list where value matched-CodePudding

I have two lists which are following.

characteristic  = ['length', 'width', 'height', 'Thread length', 'space']
value = ['length 34','width ab23','Thread length 8ah','space','height 099']

I have written a loop.

temp_str = {}



for x in characteristic:

  for z in value:  

      if x in z:

        temp_str = z.replace(x,'')

        temp_str  = ','

        print(temp_str)

I am getting output:

34,
Thread  8ah,
 ab23,
 099,
 8ah,
,

but in real I want output like following

34,ab23,099,8ah,

Try the following:

characteristic  = ['length', 'width', 'height', 'Thread length', 'space']
value = ['length 34','width ab23','Thread length 8ah','space','height 099']
temp_str = ''

for x in characteristic:
    for z in value:  
        if z.startswith(x) and z!=x:
            temp_str  = z.split(' ')[-1]
            temp_str  = ','
print(temp_str)

Output:

34,ab23,099,8ah,

Note: space was ignored because it was not included in your required output

CodePudding user response：

You could use a nested list comprehension, checking if the values in value start with the characteristics from characteristic:

result = ','.join(v.replace(c, '') for c in characteristic for v in value if v.startswith(c))

Output:

 34, ab23, 099, 8ah,

Note that space appears in value with no value attached; hence the empty field in the string.
