String ConcatenationTo concatenate, or combine, two strings you can use the + operator.Example Merge variable a with variable b into variable c: a = "Hello"b = "World"c = a + b print(c) Try it Yourself » Example To add a space between them, add a " ": a = "Hello"b = ...
We're using the plus operator to concatenate these strings.But since they're all string literals, we could instead rely on implicit string concatenation:long_string = ( "This is a very long string that goes on and on " "and might even wrap to the next line in your editor, " "which ...
Finally, we use a string concatenation operator to transform a list to a string. list2string4.py #!/usr/bin/python words = ['There', 'are', 3, 'chairs', 'and', 2, 'lamps', 'in', 'the', 'room'] msg = '' for word in words: msg += f'{word} ' print(msg) ...
可以使用+ 或者str.join来进行合并 # Implicit string concatenation>>> f"{123}" " = " f"{100}" " + " f"{20}" " + " f"{3}"'123 = 100 + 20 + 3'# Explicity concatenation using '+' operator>>> f"{12}" + " != " + f"{13}"'12 != 13'# string concatenation using `st...

1. C++ ‘+’ operator for String Concatenation C++'+' operatorcan be used to concatenate two strings easily. The ‘+’ operatoradds the two input stringsandreturns a new stringthat contains theconcatenated string. Syntax: string1 Example: ...
Python must have a better and cleaner way.Note: To learn more about string concatenation in Python, check out the Efficient String Concatenation in Python tutorial.The modulo operator (%) came to make the syntax a bit better:Python >>> "Hello, %s! Today is %s." % (name, day) '...
Python String concatenation: The '+' operator is used to concatenate two strings. >>> a = "Python" + "String" >>> print(a) PythonString >>> You can also use += to concatenate two strings. >>> a = "Java" >>> b = "Script" ...
1.operator[]与at operator[]:返回索引处的字符,不进行边界检查。 at:返回索引处的字符,进行边界检查,超出范围会抛出异常。 #include <string> #include <iostream> int main() { std::string str = "Hello"; char c1 = str[1]; // 不进行边界检查 ...
