In the previous article, we have discussed Python Program to Find the Shortest Word in a String

Given a string and the task is to check whether the given string contains at least one number in it.

**Examples:**

**Example1:**

**Input:**

Given String = "Hello 123 this is BTechGeeks online Platform "

**Output:**

Yes, the above given string has at least one digit in it

**Example2:**

**Input:**

Given String = "good morning btechgeeks"

**Output:**

No, the above-given string doesn't have at least one digit in it

## Program to Check if a String Contains at least One Number in Python

Below are the ways to check whether the given string contains at least one number in python:

### Method #1: Using For Loop (Static Input)

**Approach:**

- Give the string as static input and store it in a variable.
- Take a variable say
**k**and initialize its value to 0. - Calculate the length of the given string using the len() functionÂ store it in another variable.
- Loop from 0 to the length of the given string using the for loop.
- Check if the character present at the iterator value of the given string string is greater than or equal to 0 and less than or equal to 9 using the if conditional statement.
- If the statement is true, then increment the value of the above-initialized
**kÂ**by 1. - Exit the loop.
- Check if the value of k is greater than or equal to 1 using the if conditional statement.
- If the statement is true, then print “Yes, the above-given string has at least one digit in it”.
- Else printÂ “No, the above-given string doesn’t have at least one digit in it”.
- The Exit of the program.

**Below is the implementation:**

# Give the string as static input and store it in a variable. gvn_str = "Hello 123 this is BTechGeeks online Platform " # Take a variable say k and initialize its value to 0. k = 0 # Calculate the length of the given string using the len() function. # store it in another variable. str_lengt = len(gvn_str) # Loop from 0 to the length of the given string using the for loop. for itr in range(0, str_lengt): # Check if the character present at the iterator value of the given string string is # greater than or equal to 0 and less than or equal to 9 using the if # conditional statement. if gvn_str[itr] >= '0' and gvn_str[itr] <= '9': # If the statement is true, then increment the value of the above-initialized kÂ by 1. # Exit the loop. k += 1 # Check if the value of k is greater than or equal to 1 using the if conditional statement. if k >= 1: # If the statement is true, then print "Yes, the above-given string has at least one # digit in it". print("Yes, the above given string has at least one digit in it") else: # Else printÂ "No, the above-given string doesn't have at least one digit in it". print("No, the above-given string doesn't have at least one digit in it")

**Output:**

Yes, the above given string has at least one digit in it

### Method #2: Using For loop (User Input)

**Approach:**

- Give the string as user input using the input() function and store it in a variable.
- Take a variable say
**k**and initialize its value to 0. - Calculate the length of the given string using the len() functionÂ store it in another variable.
- Loop from 0 to the length of the given string using the for loop.
- Check if the character present at the iterator value of the given string string is greater than or equal to 0 and less than or equal to 9 using the if conditional statement.
- If the statement is true, then increment the value of the above-initialized
**kÂ**by 1. - Exit the loop.
- Check if the value of k is greater than or equal to 1 using the if conditional statement.
- If the statement is true, then print “Yes, the above-given string has at least one digit in it”.
- Else printÂ “No, the above-given string doesn’t have at least one digit in it”.
- The Exit of the program.

**Below is the implementation:**

# Give the string as user input using the input() function and # store it in a variable. gvn_str = input("Enter some random String = ") # Take a variable say k and initialize its value to 0. k = 0 # Calculate the length of the given string using the len() function. # store it in another variable. str_lengt = len(gvn_str) # Loop from 0 to the length of the given string using the for loop. for itr in range(0, str_lengt): # Check if the character present at the iterator value of the given string string is # greater than or equal to 0 and less than or equal to 9 using the if # conditional statement. if gvn_str[itr] >= '0' and gvn_str[itr] <= '9': # If the statement is true, then increment the value of the above-initialized kÂ by 1. # Exit the loop. k += 1 # Check if the value of k is greater than or equal to 1 using the if conditional statement. if k >= 1: # If the statement is true, then print "Yes, the above-given string has at least one # digit in it". print("Yes, the above given string has at least one digit in it") else: # Else printÂ "No, the above-given string doesn't have at least one digit in it". print("No, the above-given string doesn't have at least one digit in it")

**Output:**

Enter some random String = good morning btechgeeks No, the above-given string doesn't have at least one digit in it
