Python error: TypeError: unsupported operand type(s) for : 'int' and 'str', what is the solution?

When using Python for programming development, we often encounter various errors. Among them, TypeError is one of the common error types. When we try to use the operator in the code to add an integer and a string, the error "TypeError: unsupported operand type(s) for : 'int' and 'str'" will appear.

This error means that for the operator, integers and strings are incompatible operand types. In fact, operators in Python behave differently between different data types. When we use the operator on two integers or two strings, it performs the corresponding addition operation. However, when we try to use the operator on an integer and a string, the Python interpreter cannot recognize this operation and reports an error.

So, how do we solve this problem? Below we give several solutions.

Method 1: Use the str() function to convert an integer to a string

num = 10
text = "Hello, World!"

result = str(num) + text
print(result)

In this example, we first use the str() function to convert the integer num to a string type, and then Concatenate two strings. This will avoid TypeError errors.

Method 2: Use formatted string (f-string)

num = 10
text = "Hello, World!"

result = f"{num} {text}"
print(result)

In this example, we use the formatted string (f-string) method to combine num and text Format to string type and use spaces for concatenation. This will avoid TypeError errors.

Method 3: Use the string formatting operator (%)

num = 10
text = "Hello, World!"

result = "%d %s" % (num, text)
print(result)

In this example, we use the string formatting operator (%) to convert the integer num and the string text for the splicing operation. %d represents the integer type, and %s represents the string type. By passing num and text as parameters into the string for formatting, you can avoid the problem of TypeError.

Through the above three methods, we can solve the error problem of "TypeError: unsupported operand type(s) for : 'int' and 'str'". Among them, Method 1 and Method 2 are more commonly used, and you can choose the solution that suits you according to the specific situation.

Summary:

In Python programming development, when we try to use operators to add integers and strings, "TypeError: unsupported operand type(s) for : 'int" will be raised ' and 'str'" error. In order to solve this problem, we can use the str() function to convert the integer to a string, or use the format string (f-string) or the string formatting operator (%) to perform string formatting and splicing operations. Through these solutions, we can successfully avoid the problem of TypeError errors.
