You can use the ‘+’ operator to concatenate strings and variables in Python. But concatenate string and integer variable, you need to convert integer variable to string and then concatenate using the ‘+’ operator.
If you want a merge 2 strings and store value in another variable then use new_String= first_string + second_string.
Python concatenates string and variable
Simple example code.
var1 = 100
var2 = ' John'
# concatenation string and string variable
res1 = 'Hello' + var2
print(res1)
# concatenation string and int variable
res2 = str(var1) + var2
print(res2)Output:
If you try to combine a string and a number, Python will give you an error:
x = 5
y = "John"
print(x + y)
Output: TypeError: unsupported operand type(s) for +: ‘int’ and ‘str’
Alternatively, you can use formatted strings (introduced in Python 3.6 and later) or the str.format() method for more readability:
Using formatted strings:
name = "Alice"
age = 25
# Using formatted string
message = f"Hello, my name is {name} and I am {age} years old."
print(message)
Using str.format() method:
name = "Alice"
age = 25
# Using str.format() method
message = "Hello, my name is {} and I am {} years old.".format(name, age)
print(message)
