Program for Python String isdecimal() Method

Python / By

In the previous article, we have discussed Python Program for gamma() Function
isdecimal() Function in Python:

If all of the characters are decimals(0-9), the isdecimal() method returns True.

On unicode objects, this method is used.

Syntax:

string.isdecimal()

Parameters: This function has no parameters.

Examples:

Example1:

Input:

Given first string = "123456789_python"
Given second string = "92567"

Output:

The above given first string is : 123456789_python
The given first string after applying isdecimal() function: False
The above given second string is : 92567
The given second string after applying isdecimal() function: True

Example2:

Input:

Given first string = "\u0039"  (#unicode for 9)
Given second string = "92567"

Output:

The above given first string is : 9
The given first string after applying isdecimal() function: True
The above given second string is : 92567
The given second string after applying isdecimal() function: True

Program for isdecimal() Function in Python

Method #1: Using Built-in Functions (Static Input)

Approach:

  • Give the first string as static input and store it in a variable.
  • Apply isdecimal() function to the given first string that returns a value true if all of the characters are decimals(0-9).
  • Store it in another variable.
  • Print the given String.
  • Print the above-given String after applying isdecimal() function.
  • Similarly, do the same for other string and print the result string.
  • The Exit of Program.

Below is the implementation:

# Give the first string as static input and store it in a variable.
gvn_fststr = "123456789_python"
# Apply isdecimal() function to the given first string that returns a value
# true if all of the characters are decimals(0-9).
# Store it in another variable.
rslt_str1 = gvn_fststr.isdecimal()
# Print the given String
print("The above given first string is :", gvn_fststr)
# Print the above given String after applying isdecimal() function.
print("The given first string after applying isdecimal() function:", rslt_str1)
# Similarly do the same for other string and print the result string.
gvn_scndstr = "92567"
rslt_str2 = gvn_scndstr.isdecimal()
print("The above given second string is :", gvn_scndstr)
print("The given second string after applying isdecimal() function:", rslt_str2)

Output:

The above given first string is : 123456789_python
The given first string after applying isdecimal() function: False
The above given second string is : 92567
The given second string after applying isdecimal() function: True

Method #2: Using Built-in Functions (User Input)

Approach:

  • Give the first string as user input using the input() function and store it in a variable.
  • Apply isdecimal() function to the given first string that returns a value true if all of the characters are decimals(0-9).
  • Store it in another variable.
  • Print the given String.
  • Print the above-given String after applying isdecimal() function.
  • Similarly, do the same for other string and print the result string.
  • The Exit of Program.

Below is the implementation:

# Give the first string as user input using the input() function and store it in a variable.
gvn_fststr = input("Enter some Random String = ")
# Apply isdecimal() function to the given first string that returns a value
# true if all of the characters are decimals(0-9).
# Store it in another variable.
rslt_str1 = gvn_fststr.isdecimal()
# Print the given String
print("The above given first string is :", gvn_fststr)
# Print the above given String after applying isdecimal() function.
print("The given first string after applying isdecimal() function:", rslt_str1)
# Similarly do the same for other string and print the result string.
gvn_scndstr = input("Enter some Random String = ")
rslt_str2 = gvn_scndstr.isdecimal()
print("The above given second string is :", gvn_scndstr)
print("The given second string after applying isdecimal() function:", rslt_str2)

Output:

Enter some Random String = goodmorning456288729
The above given first string is : goodmorning456288729
The given first string after applying isdecimal() function: False
Enter some Random String = 90876123
The above given second string is : 90876123
The given second string after applying isdecimal() function: True
