在Python中返回chr（ord（'A'））的值
1）Pythonord()功能
ord()function是Python中的库函数，它接受一个字符并返回其ASCII值。
示例
print(ord('A')) //返回652）Pythonchr()功能
chr()function是Python中的一个库函数，它接受一个值（ASCII码）并返回字符。
示例
print(chr(65)) //返回A
chr（ord（'A'））的返回值
语句chr（ord（'A'））求值–ord（'A'）将返回65，然后chr(65)将返回ASCII代码65的字符值，因此将返回'A'。
Python代码演示示例chr()和ord()职能
#python代码演示示例
# chr() and ord() function
#打印ASCII码
c = 'A'
print("ASCII value of " + c + " is = ", ord(c))
c = 'X'
print("ASCII value of " + c + " is = ", ord(c))
c = 'a'
print("ASCII value of " + c + " is = ", ord(c))
c = 'z'
print("ASCII value of " + c + " is = ", ord(c))
#打印字符
val = 65
print("CHAR value of ", val, " is = " + chr(val))
val = 88
print("CHAR value of ", val, " is = " + chr(val))
val = 97
print("CHAR value of ", val, " is = " + chr(val))
val = 122
print("CHAR value of ", val, " is = " + chr(val))
#chr（ord（'A'）
print("value of the statement is: " + chr(ord('A')))输出结果
ASCII value of A is = 65 ASCII value of X is = 88 ASCII value of a is = 97 ASCII value of z is = 122 CHAR value of 65 is = A CHAR value of 88 is = X CHAR value of 97 is = a CHAR value of 122 is = z value of the statement is: A
