# 使用f-string插入变量 print(f"{first_name} {last_name} was born in {year_of_birth}.") 输出: Ada Lovelace was born in 1815. f-string还支持格式化选项,如指定宽度、精度等,使输出更加精确。 示例代码: pi = 3.141592653589793 # 使用f-string格式化浮点数 print(f"The value of pi is approximat...

5 f-string(自Python 3.6起) f-string是一种现代且强大的字符串格式化方式,它允许你在字符串内部直接嵌入表达式。 >>> name = "Alice" >>> print(f"你好,{name},欢迎来到Python世界!") 你好,Alice,欢迎来到Python世界! 特色:f-string提供了即时计算表达式的能力,让代码更加简洁易读。 6 format方法 str.for...
An object of the None data type can be, however, represented as an empty string in python by converting it into a string data type. This tutorial demonstrates
string S[start:end]. Optional arguments start and end are interpreted as in slice notation. 查找子字符串 sub 在字符串中出现的次数,可选参数,开始 和 结束 可理解为切片 ''' 1. 2. 3. 4. 5. 6. 7. print(s.count('and',1,3)) ...
I will leave this to you to run and explore the output. Similarly, you can also use other loops in python like thewhileloop to get a similar output. 4. Printing List as a String If you wanted to print the list as a string, you can use thejoin()toconvert the list to a stringand...

Usef-stringsMethod to Print a String and Variable in Python 3.6 and Above If you are using Python 3.6 and above,f-stringsmethod can be used. Thefletter indicates that the string is used for the purpose of formatting. It is the same as the simpleprintmethod in Python. However, in this...
File "<string>", line 1, in <module> C:\Users\Administrator> 果然Python在65001的CMD下,输出任何非ASCII的字符都会直接报错(return?)。搜了下Python的bug tracker,开发者说这是Windows的bug,具体来说是在CP65001下,Win对Unicode字符错误地按ANSI来准备buffer,导致buffer大小不足导致。
print("Python", "是", "有趣的") 效果:Python 是 有趣的,逗号自动添加了空格。 3. 格式化字符串(f-string,Python 3.6+) 让变量直接嵌入字符串。 name = "小明" print(f"欢迎,{name}!") 亮点:清晰,直观。 4. 使用sep参数 改变多个参数间的分隔符。
