Python error. cant convert int object to "str" imlicitly (Totally confused beginner here) [duplicate]

This question already has answers here:
Making a string out of a string and an integer in Python [duplicate]
(5 answers)
Closed 4 years ago.
So i decided to make a small string of code that converts your age into lion years (Basically multiplicating your age by 5).
The problem i have is i cant get it to take the age as an integer and input, that or i cant make it print the "lionage" integer below.
Code and error sign below:
name = input ("please type your name in: ")
age = int(input ("please type your age in: "))
age = int(age)
five = int(str(5))
lionage = int(age*five)
print ("Hello " + name + "! Your age is " + age + " but in lion years it's " + str(lionage) + " years")
Error: can't convert 'int' object to str implicitly
I may be wrong on what I got wrong in the code.
(By the way, please prioritize giving me an answer of why its going wrong and how I can fix it simplifying the code to make it smaller. (i want to learn that myself, thanks :) )

Python can print number, string, ... pretty much anything as long as types are not mixed up. In your case, age is a number and the rest of the line you want to print is a string. You need to convert your number to a string by adding str(age) instead of just age.

Age is a integer and you trying to concat with an string. In python, you cannot do that directly.
print ("Your age is " + age)) # <- wrong answer
you must convert age to string before concating
print ("Your age is " + str(age)) # <- Correct answer

Around all variables add str().
For example:
a = 21
print("Your age is " + str(a))
This would output "Hello World" (without speech marks).

I have to write a program that reads in a whole number and prints out that number divided by two. This is my code:
a= int(input("Number: "))
h= a/2
print("Half number: " + h)
But I keep getting this
Number: 6
Traceback (most recent call last):
File "program.py", line 3, in <module>
print("Half number: " + h)
TypeError: Can't convert 'float' object to str implicitly
I don't see anything wrong with my code and I have no idea what the error is. Any idea what's wrong?

The expression:
"Half number: " + h
is trying to add a string to a float. You can add strings to strings:
"This string" + ", then this string"
and floats to floats:
100.0 + 16.8
but Python isn't willing to let you add strings and floats. (In the error message above, Python has processed the first string and the addition, and it now expects a string -- that's why you get the error that it can't -- or at least won't -- convert a 'float' number to a string.)
You can tell Python this is what you really want it to do in a few ways. One is to use the built-in str() function which converts any object to some reasonable string representation, ready to be added to another string:
h = 100
"You can add a string to this: " + str(h)

a= int(input("Number: "))
h= a/2
print('Half number:', h)
Without the spaces in between though

Here is a very simple way to do it.
Here's a sample solution from Grok Learning:
n = int(input('Number: '))
print('Half number:', n/2)
Here's my explanation below:
As you might've already guessed, n here is a variable. And in this code, we will be assigning some information to n. int(input('Number ')) is the statement that Python will then read, and follow. int() tells Python that the input will be an integer, and input() allows the user to input whatever they would like to input. n/2 is simply another way of saying "n divided by two". print() tells Python to print a statement, and so print('Half number:', n/2) will print out that "Half number" is simply just half of the number entered above.
Here's an example of what the output should look like:
Number: 6
Half number: 3
(In that example, the input was 6.)
So, yes, I know that you may already know this stuff but I am leaving this information for people who may visit this website in the future. The error that you had was that you used a +, when you should've used a ,. Python is pretty strict when it comes to processing what you're saying, so it didn't allow you to put a str and an int together using a +. So next time, remember to use a ,.
I hope this helps you.

ValueError: could not convert string to float

So... I have this primitive calculator that runs fine on my cellphone, but when I try to run it on Windows 10 I get...
ValueError: could not convert string to float
I don't know what the problem is, I've tried using raw_input but it doesn't work ether. Please keep in mind I'm green and am not aware of most methods for getting around a problem like this
num1 = float(input ()) #take a float and store it
chars = input () #take a string and store it
num2 = float(input ())

your code only convert string that are integers like in below statement
num1 = float(input ()) #take a float and store it ex 13
print num1 # output 13.0
if you provide 13 as a input it will give the output as 13.0
but if you provide SOMEONEE as input it will give ValueError
And it is same with the case of raw_input() but the difference is that by default raw_input() takes input as a string and input() takes input as what is provided to the function

I think this is happening because in some cases 'input' contains non-numerical characters. Python is smart and when a string only contains numbers, it can be converted from string to float. When the string contains non-numerical characters, it is not possible for Python to convert it to a float.
You could fix this a few ways:
Find out why and when there are non-numerical characters in your input and then fix it.
Check if input contains numbers only with: isdecimal()
Use a try/except
isdecimal() example:
my_input = raw_input()
if my_input.isdecimal():
print("Ok, go ahead its all numbers")
UPDATE:
Two-Bit-Alchemist had some great advice in the comments, so I put it in my answer.

How can I convert and integer into a string? [duplicate]

This question already has answers here:
How to print list item + integer/string using logging in Python
(2 answers)
Closed 7 years ago.
I am coding in Python, and have reached an error that I cannot seem to solve. Here's the part of the code that it affects.
import random
a = raw_input("Enter text")
b = random.randrange(1,101)
print (a+b)
When I try to run the code, I get the error "TypeError: cannot concatenate 'str' and 'int' objects"
I want to know how to print the result of a+b.

To answer to the question in the title, you can convert an integer into a string with str. But the print function already applies str to its argument, in order to be able to print it.
Here, your problem comes from the fact that a is a string while b is an integer. The + operator works on two strings, or two ints, but not a combination of this two types. If you have two strings, the + will mean concatenate. If you have two ints, the + will mean add. It then depends on the result you want to get.
You can convert a string to an integer by using int.
Try this code:
import random
a = int (raw_input ("Enter int "))
b = random.randrange (1, 101)
print a + b

Concatenate string and int in Python 3 .4 [duplicate]

This question already has an answer here:
How can I concatenate str and int objects?
(1 answer)
Closed 1 year ago.
I'm new to Python, so I've been running through my own set of exercises to simply start memorizing basic functions and syntax.
I'm using the PyCharm IDE and Python 3.4. I've run into an issue when running through some basic string and integer concatenation exercises. Each instance below is throwing an unsupported operand type. There are several threads on Stack Overflow that clearly states proper concatenation syntax, but the above error message continues to plague me.
print ("Type string: ") + str(123)
print ("Concatenate strings and ints "), 10

In Python 3+, print is a function, so it must be called with its arguments between parentheses. So looking at your example:
print ("Type string: ") + str(123)
It's actually the same as:
var = print("Type string: ")
var + str(123)
Since print returns nothing (in Python, this means None), this is the equivalent of:
None + str(123)
which evidently will give an error.
That being said about what you tried to do, what you want do to is very easy: pass the print function what you mean to print, which can be done in various ways:
print ("Type string: " + str(123))
# Using format method to generate a string with the desired contents
print ("Type string: {}".format(123))
# Using Python3's implicit concatenation of its arguments, does not work the same in Python2:
print ("Type string:", str(123)) # Notice this will insert a space between the parameters

Note that print is a function in Python 3. In Python 2, your first line would concatenate "Type string: " and "123" and then print them. In Python 3, you are calling the print function with one argument, which returns None, and then add "123" to it. That doesn't make any sense.
The second line doesn't generate an error in Python 2 or 3 (I've tested it with 2.7.7 and 3.2.3). In Python 2, you get
Concatenate strings and ints 10
while in Python 3, your script should only print
Concatenate strings and ints
This is because again, print is a function, and therefore you call it with the argument "Concatenate strings and ints". The , 10 makes your line a tuple of the return value of print, which is None, and 10. Since you don't use that tuple for anything, there is no visible effect.

Try format():
print("Type string: {}".format(123))
print("Concatenate strings and ints {}".format(10))

There is nothing wrong with this:
print ("Type string: ") + str(123)
print is just a function like anything else. And you're calling that function with one argument, "Type string: ", and then trying to add the result (which will be None) to the string '123'. That isn't going to work. If you wanted to add the two strings together, you have to put them into the same expression, inside the parentheses:
print("Type string: " + str(123))
Similarly:
print ("Concatenate strings and ints "), 10
This calls print with one argument, and then makes a tuple of the None returned by print and the number 10. If you want to pass 10 to the print call, it has to go inside the parentheses:
print("Concatenate strings and ints ", 10)
As gitaarik's answer points out, using str.format is more flexible, and avoids the possibility of problems like this. It also gives you code that works exactly the same way in both Python 2.6-2.7 and Python 3.x, which is pretty nice even if you aren't trying to write dual-platform/single-codebase code, because it'll be understandable even to people who only know one or the other.

I think this is a pretty cool way to concatenate a string and an int in Python:
print (f"Type string: {123}")
print (f"Concatenate strings and ints {10}")

You can do it like this:
c = 'Emerson'
d = 32
print("My name is %s and I am %d years old." %(c,d))
Result:
My name is Emerson and I am 32 years old.
