x=100print(f'{x=}') x=100 在python f-字符串里使用条件 还可以在f-字符串插入简单的if/else条件。考虑下面的示例: 点击查看代码 pass_mark=50mark_1=60mark_2=49print(f"student 1{' pass'ifmark_1>pass_markelse' fail'}")print(f"student 2{' pass'ifmark_2>pass_markelse' fail'}") 结...
Python两种输出值的方式: 表达式语句和 print() 函数。 第三种方式是使用文件对象的 write() 方法,标准输出文件可以用 sys.stdout 引用。 如果你希望输出的形式更加多样,可以使用 str.format() 函数来格式化输出值。 如果你希望将输出的值转成字符串,可以使用 repr() 或 str() 函数来实现。
>>>p = Point()>>>Point.reset(p)>>>print(p.x, p.y) 输出与前面的例子相同,因为在内部发生了完全相同的过程。 如果我们在类定义中忘记包括self参数会发生什么?Python 会报错,如下所示: >>>classPoint:...defreset():...pass...>>>p = Point()>>>p.reset() ...
print 可以自动换行,例如: 代码语言:python 代码运行次数:0 运行 AI代码解释 print("%s is %0.2f, %d is a integer" % ("PI", 3.14, 123)) # 格式同 C 语言中的 printf() print("{0} is {1}, {2} is a integer".format("PI", 3.14, 123)) print("{foo} is {bar}, {qux} is a in...

f-string可以进行合并 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 ...
