The methods you’ll explore in this section allow you to convert between a string and some composite data types by joining objects together to make a string or by breaking a string up into pieces. These methods operate on or return iterables, which are collections of objects. For example, ...
The str() function in Python is used to convert a variable value to a string. We can use both these methods together to print variable and string in same line in Python. We will convert the variable to a string and concatenate it with the string using the + operator. For example, Usin...

If you want to concatenate variables or a variable and a literal, use +:如果要连接变量或变量和文字，请使用+：>>> prefix + 'thon''Python'Strings can be indexed (subscripted), with the first character having index 0. There is no separate character type; a character is simply a string of...
'to have them joined together.') >>> text 'Put several strings within parentheses to have them joined together.' 只能对两个字面值这样操作,变量或表达式不行: >>> prefix = 'Py' >>> prefix 'thon' # can't concatenate a variable and a string literal File "<stdin>", line 1 prefix 'tho...
For example, you can compare a number and a string for equality with the == operator. However, you’ll get False as a result: Python >>> 2 == "2" False The integer 2 isn’t equal to the string "2". Therefore, you get False as a result. You can also use the != operator...

()method is then used to convert the integer value to a string, and the resulting string is concatenated with the originalstring_valueusing the+operator. Concatenation means joining two or more strings together. After concatenating the string and integer, the result is stored in the variableresult...
var2 = 'string-2' # initialize 3rd variable var3 = float(23.42) print(var1, var2, var3) The output of the following code will be. 1 string-2 23.42 So, as many item you want to print, just put them together as arguments.
