Write A Python Program To Extract The First N Characters Of A String

Given the string as an input to the Python program,  and also the value of n as to extract first n characters from a given string you have to print the first n characters out of the given string.

let's try to solve this using a python code

 

 

 

Write A Python Program To Extract The First N Characters Of A String

Let's take a variable named as text and use the input function call and ask the user to enter a string.  take another variable name as n using the input function call and ask the user to enter the value of an to extract the first n characters from a given string and then convert into integer using the type conversion.

text = input("Enter a String : ")
N = int(input("Enter Value of N : "))



Now using the if statement check if the value of n is less than 0.  if the value of an is less than 0 then print invalid Value of n using the print function call


Now using the else block print user friendly message. Now take another variable as new_text and use the string slicing method to remove the last n characters using [:N] to extract the first N characters of a given string.

Finally print the new_text variable.


if N < 0:
   print("Value of N is Invalid")
else:
   print(f"The First {N} Characters Of A String")
   new_text = text[:N]
   print(new_text)





Python code
====================
text = input("Enter a String : ")
N = int(input("Enter Value of N : "))

if N < 0:
   print("Value of N is Invalid")
else:
   print(f"The First {N} Characters Of A String")
   new_text = text[:N]
   print(new_text)





Output
===============
Enter a String : hello python
Enter Value of N : 4
The First 4 Characters Of A String
hell




Output
================
Enter a String : code with tj
Enter Value of N : -23
Value of N is Invalid




Output
================
Enter a String : code with tj
Enter Value of N : 6
The First 6 Characters Of A String
code w




Conclusion
===============
Try executing the above Python program by providing random string and integer value as an Input and then evaluate the result.
