How do I concatenate a boolean to a string in Python?
PythonStringCastingBooleanConcatenationPython Problem Overview
I want to accomplish the following
answer = True
myvar = "the answer is " + answer
and have myvar's value be "the answer is True". I'm pretty sure you can do this in Java.
Python Solutions
Solution 1 - Python
answer = True
myvar = "the answer is " + str(answer)
Python does not do implicit casting, as implicit casting can mask critical logic errors. Just cast answer to a string itself to get its string representation ("True"), or use string formatting like so:
myvar = "the answer is %s" % answer
Note that answer must be set to True (capitalization is important).
Solution 2 - Python
The recommended way is to let str.format handle the casting (docs). Methods with %s substitution may be deprecated eventually (see PEP3101).
>>> answer = True
>>> myvar = "the answer is {}".format(answer)
>>> print(myvar)
the answer is True
In Python 3.6+ you may use literal string interpolation:
>>> print(f"the answer is {answer}")
the answer is True
Solution 3 - Python
answer = True
myvar = "the answer is " + str(answer)
or
myvar = "the answer is %s" % answer
Solution 4 - Python
Using the so called f strings:
answer = True
myvar = f"the answer is {answer}"
Then if I do
print(myvar)
I will get:
the answer is True
I like f strings because one does not have to worry about the order in which the variables will appear in the printed text, which helps in case one has multiple variables to be printed as strings.
Solution 5 - Python
answer = True
myvar = 'the answer is ' + str(answer) #since answer variable is in boolean format, therefore, we have to convert boolean into string format which can be easily done using this
print(myvar)
Solution 6 - Python
answer = “True”
myvars = “the answer is” + answer
print(myvars)
That should give you the answer is True easily as you have stored answer as a string by using the quotation marks
