python - 我如何计算输入的字符串的平均长度

Question

对于我的 python 作业，程序要求用户输入三个字符串并打印输入的字符串的平均长度

我的代码:

name1 = input ("enter first string: ")
name2 = input ("enter second string: ")
name3 = input ("enter third string: ")

total_strings = (name1.split()) + (name2.split()) + (name3.split()) 

average =( len(name1) + len(name2) + len(name3) )/len(total_strings)

print("the average length is: " + str(average))

---

所以当我尝试它时，数学变得有点奇怪。

输入:

a ajhs jah sjajsh jahs jah jah jsh as

ajs jahjah sjhajsh jahs jah sjah jsh ajs

ajs ajhs jah sjahs jah sjah sjah jsh ajhs jah s

=====这里测试失败=====

enter first string: enter second string: enter third string: the average length is: 4.428571428571429

---

预期输出:

---

enter first string: enter second string: enter third string: the average length is: 41.33

在 python 2.7 中完美运行。

name1 = raw_input("enter first string: ")
name2 = raw_input("enter second string: ")
name3 = raw_input("enter third string: ")

average = (len(name1) + len(name2) + len(name3)) / 3

print("the average length is: " + str(average))

希望对您有所帮助。
