如何将字符串数字转换为int并避免转换前的字符串文本

Question

I would like to create the check condition string is string number or not so, how I can do in python

x = "String"
y = "12"

if x is string:
   print("this is string")
if y is string:
   print("this is not string")

Answer 1

You could try something like this:

array = ["String", "12"]

for item in array:
  try:
    int(item)
    print(f"{item} is not string")
  except:
    print(f"{item} is string")

Answer 2

You can use .isdigit() method to fulfill this.

x = "String"
y = "12"

if not(x.isdigit()):
   print("this is string")
if y.isdigit():
   print("this is not string")

Output:

this is string
this is not string
