I coded as follows, why it didn't compile as "my name is Maria, my age is 11." please? Thank you ;)

Question

name = "Maria"
age = 11

print(type(name), type(age))
print("my name is 'name', my age is 'age'.")

---

<class 'str'> <class 'int'>
my name is 'name', my age is 'age'.

Answer 1

There are 4 ways I think.

Using normal addition or String concatenation

print('my name is ' + name + ', my age is ' + str(age) + '.')

Using f-string

print(f'my name is {name}, my age is {age}.')

Using .format()

print("my name is {name}, my age is {age}.".format(name=name, age=age))

Using the % operator

print("my name is %s, my age is %i." % (name, age))

Answer 2

It's not necessary to add quotes for variable to assign its value.

print("my name is",name,"my age is",age)

Edit: @Wei, yeah I missed to notice it too. You can use the punctuation marks as strings using quotes and concatenate them.
So, it needs to be like this

print("My name is",name,",","My age is",age,".")

Additionally, comma adds a space by default in concatenation. Inorder to handle this problem you can use plus as concat operator. But keep in mind, you have to convert integers to string using str() when you're using + in concatenation.

print("My name is "+name+","+"My age is "+str(age)+".")

Answer 3

This should do the work :

name = "Maria"
age = 11

print('my name is ' + name + ', my age is ' + str(age))
