TypeError: ‘<‘ not supported between instances of ‘str’ and ‘int’

In Python ” TypeError: ‘<‘ not supported between instances of ‘str’ and ‘int’ ” we face this message when we try the string and integer compare or use greater than, equal and less than, +, -, /, or more then we face this error.  For example, if you want to compare the sting ( “10”) with the integer (20) but in simple language sting (“10”) is a text, not a number but integer (20) is the number and in python, we are not able to calculate string(“text”) pulse integer (20) number. To fix this error we need to convert the string into an integer then we are able to fix this error, for more clarification please see the below example.

Wrong Code

print("Welcoml to the Amol BLog love Calculator!")
name1 = input("What is Your Name?\n")
name2 = input("What is their name?\n")

combined_string = name1 + name2
lower_case_string = combined_string.lower()

t = lower_case_string.count("t")
r = lower_case_string.count("r")
u = lower_case_string.count("u")
e = lower_case_string.count("e")

true = t + r + u + e

l = lower_case_string.count("l")
o = lower_case_string.count("o")
v = lower_case_string.count("v")
e = lower_case_string.count("e")

love = l + o + v + e

love_score = str(true) + str(love)

if (love_score < 10) or (love_score > 90):
    print(f"Your love score is {love_score}, you go together like code and mentors.")
elif (love_score >= 40) and (love_score <= 50):
    print(f"Your love score is {love_score}, you are alright together.")
else:
    print(f"Your love score is {love_score}.")

Wrong code line

love_score = str(true) + str(love)

Correct code line

love_score = int(str(true) + str(love))

• Wrong action: love_score = str(true) + str(love)
• Correct action: love_score =  int(str(true) + str(love))
• Convert Str into an int.
