String isdecimal() Vs. isdigit() Vs. isnumeric() Methods
The methods isdigit(), isnumeric() and isdecimal() are in-built methods of String in python programming language, which are worked with strings as Unicode objects. These functions return either true or false.
Comparison
The comparison is based on Unicode classifications,
| isdecimal() |
isdigit() |
isnumeric() |
Example of string with decimal characters:
"12345"
"12"
"98201"
|
Example of string with digits:
"12345"
"1233"
"3"
|
Example of string with numerics:
"12345"
"½¼"
"½"

Example
str1 = "362436" # decimal characters
str2 = "3" # unicode digit
str3 = "½¼" # fractional value
print("str1 :")
print("str1.isdecimal () : ", str1.isdecimal())
print("str1.isnumeric () : ", str1.isnumeric())
print("str1.isdigit () : ", str1.isdigit())
print("str2 :")
print("str2.isdecimal () : ", str2.isdecimal())
print("str2.isnumeric () : ", str2.isnumeric())
print("str2.isdigit () : ", str2.isdigit())
print("str3 :")
print("str3.isdecimal () : ", str3.isdecimal())
print("str3.isnumeric () : ", str3.isnumeric())
print("str3.isdigit () : ", str3.isdigit())
Output
str1 :
str1.isdecimal () : True
str1.isnumeric () : True
str1.isdigit () : True
str2 :
str2.isdecimal () : True
str2.isnumeric () : True
str2.isdigit () : True
str3 :
