You may already have noticed that the first string contains letters of the alphabet, but the second string does only consist of numbers. However, let’s check this using some Python code! Example: Test for Alphabetical Letters Using the any() & isalpha() Functions ...
If you havetwo or more letters with the same frequency, then return the letter which comes first in the latin alphabet. For example -- "one" contains "o", "n", "e" only once for each, thus we choose "e". Input:A text for analysis as a string (unicode for py2.7). Output:The ...
