how are you supposed to add an integer to a string?

If what you want is mathematical addition (i.e. you'd want 1 and "2" to add to 3), then yes, you want to convert the string to an int first using int() (or, if it's not actually an integer, to float using float()). If what you want is string concatenation (i.e. you'd want 1 and "2" to add to "12"), then you'll either need to convert the integer to str first or use f strings or the format method etc. More on reddit.com

how to use int() and str() properly

Use int to parse strings to integers like int("123") == 123. Or convert stuff like floating point numbers to integers: int(123.4) == 123. Use str to obtain string representations of various objects like str(123) == "123", str([1,2,3]) == "[1, 2, 3]" and so on. More on reddit.com

How to think about integers, strings, and floats?

the difference of integers, strings, and floats integers: whole numbers with no decimal in the value, positive or negative (1, 5000, -4) floats: short for "floating-point number", anything with a decimal point (3.14, 1.0) string: anything text, always surrounded by quotation marks ("word", "3") We've used it for stuff like print(f"You are {age} years old!") Just for clarity's sake, the f there has nothing to do with floats. That's just an F-string for variable interpolation. More on reddit.com

string - Differentiating Python variables as str or int - Stack Overflow

The first point is that you need some rule that tells you which values are integers and which ones aren't. In a data set that includes things like 32s, I'm not sure it makes sense to just treat anything that could be an integer as if it were.

But, for simplicity, let's assume that is the rule you want: anything that could be an integer is. So, int(a) is already pretty close; the only issue is that it can fail. What do you do with that?

Python is designed around EAFP: it's Easier to Ask Forgiveness than Permission. Try something, and then deal with the fact that it might fail. As Cyber suggests, with a try statement:

try:
    intvalue = int(a)
except ValueError:
    # Oops, it wasn't an int, and that's fine
    pass
else:
    # It was an int, and now we have the int value
    maxvalue = max(maxvalue, intvalue)

isalpha() Returns "True" if all characters in the string are in the alphabet

isnumeric() Returns "True" if all characters in the string are numeric

so;

data="Hello World" 
print(data.isnumeric()) #it will retuns with False
print(data.isalpha())   # True

Sorry for my soulles answer, I just came here for same issue, I found a different way and wanted to share with you

good day everyone,

would anyone be able to help me figure out how to make a function to calculate a size for a circle and increase it's size by a multiple of 2,3,4 and so on with retaining it's original quotient value?

i would have a default ellipse right in the middle of the canvas with a size of 10,10

i need help to make a function to increase that size by pressing key 2 and multiply it and so on with key 3, key 4.....

i just couldnt get around how to use int() and str() properly

Use int to parse strings to integers like int("123") == 123. Or convert stuff like floating point numbers to integers: int(123.4) == 123. Use str to obtain string representations of various objects like str(123) == "123", str([1,2,3]) == "[1, 2, 3]" and so on.

First, you must understand the concept of data type. Data type defines what a variable can hold and how it works with it. a = 12 #a is integer (int) b = "12" #b is string (str) c = 1.2 #c is floating point (float) Integers can't have fractional part. Strings hold arbitrary number of characters. Floats have fractional parts, but they store only a limited number of digits. There are other types. Variable behavior depends on their types, like 12*2 is 12, but "12"*2 is "1212". 0.1+0.2 is 0.30000000000000004 (because float digits are binary, and this number has a better binary representation than 0.3). Also, Python has dynamic variable types; that means, you can change the type you store in a variable. In some other languages, a variable can hold only values of one type. Now, input() return a str. If you need to work with numbers, you first need to convert it into some numeric type, like int or float. Probably, with a circle you want to have it fractional, i.e. float: radius = float(input()) print('Circumference', radius*3.14*2)

Python String to Int

This is commonly necessary when you're receiving user input in a Python script, which always first arrives as text of the data type str. Look at the explicit type conversion example below. Again, don't worry if you don't exactly understand what's going on here, and remember to try to read it as English pseudocode. Then, see whether you can somewhat understand what the code is about: userAge = "33" userAge = int(userAge) # int stands for 'integer' print(userAge, type(userAge))
