Finding symbols in a list-CodePudding

I have a list e.g. ["1","2","n","5","n","x","0","v","-","a","l","4","1","v","m","z","o","5","%","d",";","a","m","6"] I want to print out the elements that are a letter or special symbol. how do I do this?

You can use isdigit(). Like so:

some_str = "12a"

for i in some_str:
   print(i.isdigit())

# outputs
True
True
False

Python comes with an isnumeric() method that returns true when a string is a number. In the case you listed you could try:

string_list = ["1","2","n","5","n","x","0","v","-","a","l","4","1","v","m","z","o","5","%","d",";","a","m","6"]
for value in string_list:
    if not value.isnumeric():
        print(value)

...which would output

n
n
x
v
-
a
l
v
m
z
o
%
d
;
a
m
