While loop python resulting in infinite loop

Question

def generate_n_chars(n,s="."):
 res=""
 count=0
 while count < n:
 count=count+1
 res=res+s
 return res
print generate_n_chars(raw_input("Enter the integer value : "),raw_input("Enter the character : "))

I am beginner in python and I don't know why this loop going to infinity. Please someone correct my program

• Jacques Kvam: Can you add what inputs you used?
• Ignacio Vazquez-Abrams: You're comparing a number with a string.

Answer 1

The reason is because the input will be evaluated and set to a string. Therefore, you're comparing two variables of different types. You need to cast your input to an integer.

def generate_n_chars(n,s="."):
 res=""
 count=0
 while count < n:
 count=count+1
 res=res+s
generate_n_chars(int(raw_input("Enter the integer value : ")),raw_input("Enter the character : "))

Answer 2

def generate_n_chars(n, s = "."):
 res = ""
 count = 0
 while count < n:
 count = count + 1
 res = res + s
 return res
print generate_n_chars(input("Enter the integer value : "), raw_input("Enter the character : "))

Here input("Enter the integer value : ") input instead of raw_input

raw_input() => https://docs.python.org/2/library/functions.html#raw_input

input() => https://docs.python.org/2/library/functions.html#input
