然而,由于浮点数的内部存储方式,我们有时会遇到一些显示问题。在实际应用中,我们需要根据具体情况选择合适的方法来处理浮点数的显示。 参考文献: [Python Official Documentation]( [Python Tutorial]( 以下是状态图: stateDiagram [*] --> Print Print --> FormatString Print --> RoundFunction FormatString -->...
python内置函数有：abs、divmod、max、min、pow、round、sum、bool、int、float、complex、str、bytearray、bytes、memoryview、ord、oct、tuple、map等等。map，其中func为函数名，可为lambda匿名函数，iterable为可迭代对象。此函数会将可迭代对象中的每一位元素作为参数传递到func中，并将func的计算结果加入到新列表内...
round() Function in Python The round() function rounds off a floating-point number to a specified number of decimal places. Example 1: Python 1 2 3 4 # Rounding a floating-point number num = 3.5678 print(round(num, 2)) Output: Explanation: Here, round() rounds off the number to ...
round(x [,n]) x rounded to n digits from the decimal point. seed([x]) Sets the integer starting value used in generating random numbers. Call this function before calling any other random module function. Returns None. shuffle(lst) Randomizes the items of a list. Returns None. sin...
