![]() ![]() Suggested reading: String Manipulation String Formatting in Python After execution of the join() method, we get the desired output. For this, we invoked the join() method on a string containing the space character and passed a list of all the input strings. In the above example, we have concatenated three strings using the space character. The concatenated string is: Python For Beginners You can observe this in the following example. After execution, it concatenates all the strings in the list by the separator and returns a new string. The join() method, when invoked on a separator string, takes a list of strings as its input argument. If you want to concatenate the strings separated by a string or character as a separator, you can use the join() method. String Concatenation Using The join() Method As 3.5 is a floating point number, you can observe that the program runs into a TypeError exception saying that we cannot multiply a sequence by a non-int type of float. In the above code, we have tried to multiply a string by 3.5. TypeError: can't multiply sequence by non-int of type 'float' In this case, the program will run into a TypeError exception as shown in the following example. You cannot multiply a string with a floating point number. Even if you multiply a string with a negative integer, you will get an empty string in the output. Hence, we get an empty string in the output. In the above code, we have multiplied the original string with 0. If you multiply a string by 0, you will get an empty string as shown below. Hence, we get a new string with the original string repeated three times. In the above code, we have multiplied the original string by 3. The output string is: PythonForBeginnersPythonForBeginnersPythonForBeginners When we multiply a string with an integer N, the string is repeated N times and we get a new string object. Hence, the program executes successfully and we get the output. Then, we concatenated the strings using the + operator. In this example, we first converted the integer 1117 to a string using the str() function. The concatenated string is: PythonForBeginners1117 Then, you can perform string concatenation on the two Python strings as shown below. If you still want to merge a string and an integer, you will need to convert the integer to a string. Due to this, the program runs into a TypeError exception. In the above output, you can observe that we have tried to concatenate the string “PythonForBeginners” and the integer 1117. TypeError: can only concatenate str (not "int") to str TypeError Traceback (most recent call last)Ħ print("The concatenated string is:",newStr) Output: The string is: PythonForBeginners If you try to concatenate a string and an integer, the program will run into a Python TypeError exception as shown below. These are considered two separate types of objects. ![]() Python doesn’t support concatenating a string and an integer. The concatenated string is: PythonForBeginners Concatenate String and Integer in Python For instance, you can concatenate three strings in Python as shown below. You can also concatenate more than two strings using the + operator as long as all the operands are valid strings. Then, we used the + operator to concatenate both strings. In the above code, we have created two string objects str1 and str2. The concatenated string is: PythonForBeginners Print("The concatenated string is:",newStr) When writing code, that would look like this: str1="Python" In order to merge two strings into a single object, you may use the “+” operator. ![]()
