One line python code to remove all the strings that doesn't start with T or t and if they contain number greater then 6

Eg:

List=["tata1","tata2","Tata3","mdkjd","djhdj","Tata8","t9","t2"]

Output should be:["tata1","tata2","Tata3","t2"]

I tried :

content = [item for item in List if terminal.lower().startswith('t')]

My doubt if I can append one more condition with the if I used in my code?

If yes, how?

I tried writing but it gives error.

Solution

  • You can use and to test multiple conditions.

    >>> [i for i in l if i and i[0] in 'tT' and all(j not in i for j in '789')]
['tata1', 'tata2', 'Tata3', 't2']

    So from left to right this will test:

    These conditions will "short circuit" meaning upon the first test failing, there is no need to check the following conditions as False and (anything) is always False.
