Convert strings to int or float in Python 3?

Question

``` integer = input("Number: ") rslt = int(integer)+2 print('2 + ' + integer + ' = ' + rslt) double = input("Point Number: ") print('2.5 + ' +double+' = ' +(float(double)+2.5)) ``` Gives me ``` Traceback (most recent call last): File "C:\...", line 13, in <module> print('2 + ' + integer + ' = ' + rslt) TypeError: Can't convert 'int' object to str implicitly ``` I'm fairly new to programming and my background is mostly just the basics of C# so far. I wanted to try to learn Python through doing all my C# school projects on Python. I'm used to the simple syntax of C# which would look something like this: ``` int integer = Convert.ToInt32(Console.ReadLine()) ``` or ``` double double = Convert.ToDouble(Console.ReadLine()) ``` Which takes a user input string and converts it to what I specified. I think I read py2.x has a command called raw_input that works a bit better than the input command of py3.x in this regard. I was trying to find myself a similar format as the one I'm used to in C# t…

Accepted Answer

You have to convert the integer into a string:

```
print('2 + ' + str(integer) + ' = ' + str(rslt))
```

Or pass it as an argument to `print` and print will do it for you:

```
print('2 +', integer, '=', rslt)
```

I would do it using string formatting:

```
print('2 + {} = {}'.format(integer, rslt))
```
