定义一个字符串“I like Python very much 2333 because Python is very cute 666.”,判别该字符串中数字字符的个数,并将第一次出现的Python替换成你偶像的名字并输出新字符串。 print("1 到 到 N 求和结果: ", sum)

该字符串中数字字符的个数为6个,第一次出现的Python将被替换成我偶像的名字后,新字符串为“I like Taylor Swift very much 2333 because Python is very cute 666.”。但是,你的代码中没有定义变量N,所以无法计算1到N的求和结果。

python中定义一个字符串“I like Python very much 2333 because Python is very cute 666.”,判别该字符串中数字字符的个数,并将第一次出现的Python替换成你偶像的名字并输出新字符串。 print("1 到 到 N 求和结果: ", sum)写出代码
s = "I like Python very much 2333 because Python is very cute 666."
count = 0
for char in s:
if char.isdigit():
count += 1
new_s = s.replace("Python", "Tom Hanks", 1)
print("数字字符的个数为:", count)
print("替换后的字符串为:", new_s)
# 代码中的 sum 变量没有定义,无法输出结果。
