Therefore when we finally print the result after the for loop the output on the console is ‘1 2 3 4 5 6 7 8 9 10’. And the same process goes on until i=10 and finally after the last iteration result=1 2 3 4 5 6 7 8 9 10.Since i=1, on the first iteration finally result=1.On first iteration when the variable i=1,then the variable ,str(i) converts the ‘i’ which is an integer value to a string value.On each for loop iteration this ‘i’ variable is going to take up values from 1 to 10.so range(1,11) is going to generate a list of numbers from 1 to 10.This list of numbers is generated using the range function.The for loop is being used to iterate over a list of numbers.First of all a variable ‘result’ is assigned to an empty string.Here's a line-by-Line explanation of how the above code works: Here's how to print 1 2 3 4 5 6 7 8 9 10 using a single string: result = "" Print("Hello, I am " + str(age) + " years old") Here's a simple concatenation example: age = 18 The Correct Way to Convert a String to an Integer in Python Here, TypeError: must be str, not int indicates that the integer must first be converted to a string before it can be concatenated. The error that shows up is: Traceback (most recent call last): You can convert an integer or float to a string with str() this way: myint 45 myfloat 34.8 Convert both to string convertedmyint str(myint. The programming language provides several functions you can use to convert any of these data types to the other. String = "Hello, I am " + age + " years old" Python’s primitive data types include float, integer, Boolean, and string. Programmers coming from other programming languages may attempt to do the following string concatenation, which will produce an error: age = 18 The Wrong Way to Convert a String to an Integer in Python Unlike many other programming languages out there, Python does not implicitly typecast integers (or floats) to strings when you concatenate them to strings.įortunately, Python has a handy built-in function str() which will convert the argument passed in to a string format.
