实例分析——温度转换

(Case Study – Temperature Conversion)

目的为将随意给出的华氏度或摄氏度温度实现相互转换。

The purpose is to convert the temperature given arbitrarily to Fahrenheit or Celsius to each other.


#表示注释

TempStr、C、F为变量名,通常用“=”进行赋值。图中,将随意输入的温度赋值给TempStr,C、F再由转换关系TempStr得到。

TempStr, C, F are variable names, usually assigned with "=". In the figure, the randomly entered temperature is assigned to TempStr, and C and F are obtained by the conversion relationship TempStr.

input表示输入信息

input represents the input information

索引:返回字符串中单个字符,如图中TempStr[-1],表示返回TempStr字符串中最后一个字符

Index: Returns a single character in a string, as shown in TempStr[-1] in the figure, indicating that the last character in the TempStr string is returned

切片:返回字符串中一段字符串。如图中TempStr[0:-1]表示返回TempStr字符串从第0个字符至倒数第二个字符。

Slice: Returns a piece of string in a string. As shown in the figure, TempStr[0:-1] indicates that the TempStr string is returned from the 0th character to the penultimate character.

分支语句:使用保留字if、elif、else构成条件判断的分支语句。

保留字所在行最后存在的一个冒号(:)

冒号及后续缩进用来表示后续语句与条件的所属关系。

in表示判断TempStr[-1]是否与in后面的一致。

Branch statement: Use the reserved words if, elif, and else to form a branch statement that constitutes conditional judgment.

A colon (:)) at the end of the line where the reserved word is located

Colons and subsequent indents are used to indicate the ownership of subsequent statements and conditions.

in indicates whether TempStr[-1] is consistent with the one following in.

eval函数:去掉参数最外侧引号并执行余下语句。如eval(TempStr[0:-1]),如果TempStr[0:-1]的值为“28.7”,则输出的是28.7。

EVAL function: Remove the outermost quotation marks of the argument and execute the rest of the statement. For example, eval(TempStr[0:-1]), if the value of TempStr[0:-1] is "28.7", the output is 28.7.
