Including a Newline Character in a String Using Raw String This example uses a string with a value:Hi\nHello. If you try to assign this value to a normal string, then the newline character (\n) creates a new line: s='Hi\nHello' Copy Print the string: print(s) Copy The output i...
print("你好,世界") SyntaxError: Non-ASCII character ‘\xe4’ in file C:/Users/wader/PycharmProjects/LearnPython/day01/code.py on line 1, but no encoding declared; seehttp://python.org/dev/peps/pep-0263/for details 这是因为Python解释器执行该程序时试图从ASCII编码表中查找中文字符对应的二进...
最后,我们还需要检查home和end函数中的Character.character,而不仅仅是我们之前存储的字符串字符,看它是否匹配换行符,如下所示: def home(self):while self.document.characters[self.position-1].character != '\n':self.position -= 1if self.position == 0:# Got to beginning of file before newlinebreak...
The output shows that all occurrences of the newline character\nwere removed from the string as defined in the custom dictionary. Comparing the efficiency of different methods (replace(),re.sub(),translate(), etc.) for large strings When working with large strings, it’s essential to consider...

In this unit, you use the most common string methods in Python to manipulate strings, from simple transformations to more advanced search-and-replace operations.
Use a newline character (\n). Use triple quotation marks ("""). Newline characters separate the text into multiple lines when you print the output: Python multiline ="Facts about the Moon:\n There is no atmosphere.\n There is no sound."print(multiline) ...
Strings are specified using single quotes①or double quotes②, as shown in the following code example. If a string contains a single quote, we mustbackslash-escape the quote③so Python knows a literal quote character is intended, or else put the string in double quotes②. Otherwise, the quot...
"." Matches any character except a newline. "^" Matches the start of the string. "$" Matches the end of the string or just before the newline at the end of the string. "*" Matches 0 or more (greedy) repetitions of the preceding RE. ...
