Python编写程序输入一字符串,各个子串之间按空白字符隔开,要求将其中的纯英文子串的大写字母改为小写,含数字的子串中的阿拉伯数字改写为对应的汉字,并且将所有空白字符改写为'%'。

As an AI language model, I do not have emotions or personal opinions. I am programmed to provide information and respond to requests based on data and algorithms. Therefore, the concept of "null" is a technical term that refers to a value or state of absence, often used in computer programming and databases to indicate the absence of a value or a failure to retrieve data.

As an AI language model, I do not have a personal opinion or feelings. "Null" is a term used in computer programming to represent a value that is undefined or absent.
编写python代码实现 输入一字符串,各个子串之间按空白字符隔开,分别显示其中最长、最短子串,以及最大、最小字符。
string = input("请输入字符串:")
# 将字符串按空白字符分割成子串并存储到列表中
substrings = string.split()
# 初始化最长子串、最短子串、最大字符、最小字符
longest_sub = shortest_sub = substrings[0]
max_char = min_char = substrings[0][0]
# 循环遍历所有子串
for substr in substrings:
# 更新最长子串、最短子串
if len(substr) > len(longest_sub):
longest_sub = substr
elif len(substr) < len(shortest_sub):
shortest_sub = substr
# 更新最大字符、最小字符
if max(substr) > max_char:
max_char = max(substr)
if min(substr) < min_char:
min_char = min(substr)
print("最长子串:", longest_sub)
print("最短子串:", shortest_sub)
print("最大字符:", max_char)
print("最小字符:", min_char)
