Is there a short way to remove all strings in a list that contains numbers?
For example
my_list = [ 'hello' , 'hi', '4tim', '342' ]
would return
my_list = [ 'hello' , 'hi']

The method unique() from Numpy module can help us remove duplicate from the list given. The Pandas module has a unique() method that will give us the unique elements from the list given. The combination of list comprehension and enumerate is used to remove the duplicate elements from the list.
To remove duplicates using for-loop , first you create a new empty list. Then, you iterate over the elements in the list containing duplicates and append only the first occurrence of each element in the new list. The code below shows how to use for-loop to remove duplicates from the students list. Voilà!
How to Remove an Element from a List Using the remove() Method in Python. To remove an element from a list using the remove() method, specify the value of that element and pass it as an argument to the method. remove() will search the list to find it and remove it.
1) Sort the elements. 2) Now in a loop, remove duplicates by comparing the current character with previous character. 3) Remove extra characters at the end of the resultant string.
Without regex:
[x for x in my_list if not any(c.isdigit() for c in x)]
I find using isalpha() the most elegant, but it will also remove items that contain other non-alphabetic characters:
Return true if all characters in the string are alphabetic and there is at least one character, false otherwise. Alphabetic characters are those characters defined in the Unicode character database as “Letter”
my_list = [item for item in my_list if item.isalpha()]
