PYTHON STRING FORMAT CODE
The code for that would look like this: > print ‘red’ + str ( 3) red3 > To make this possible, we can convert the number into a string using the appropriate function. It makes sense why the error happens when you look at it this way. Python cannot add a word and number together. An integer on the other hand is a recorded number value that doesn’t have a decimal point. In layman’s terms, a string can be any recorded characters but it’s most commonly used to store words and information. This is where we are trying to concatenate a string and integer object, and it failed. In addition, we can see when trying to combine ‘red’ and 3 the interpreter spits out an error. This is important, so be sure to record it to memory.
Notice how multiplying the string “red” three times returns the value “redredred”. > print ‘red’ + ‘yellow’ Redyellow > print ‘red’ * 3 Redredred > print ‘red’ + 3 Traceback (most recent call last): File “”, line 1, in TypeError : cannot concatenate ‘ str ’ and ‘ int ’ objects >įor reference, the “>” characters indicate where the interpreter is requesting a command. It was copied from David Bau’s personal website. The following example shows what happens when you try to merge a string and integer object. So, if you want to merge the two, you will need to convert the integer to a string. These are considered two separate types of objects. One thing to note is that Python cannot concatenate a string and integer. The final line in this code is the concatenation, and when the interpreter executes it a new string will be created. When writing code, that would look like this: str1 = “Hello” str2 = “World” str1 + str2 In order to merge two strings into a single object, you may use the “+” operator.
Obviously, this is because everything in Python is an object – which is why Python is an objected-oriented language. The new string that is created is referred to as a string object. In Python, there are a few ways to concatenate – or combine – strings. After, we will explore formatting, and how it works. There are different ways to do that, and we will discuss the most common methods.
