我试图搜索文本文件并确定文本文件中有多少行、元音、辅音和数值/字符。我的元音、辅音和数字输出值似乎没有正确计算。线路输出总计已正确计算。ein = input("Please enter file name: ")vowels = set("AEIOUaeoiu")cons = set("BCDFGHJKLMNPQRSTVWXYZbcdfghjklmnpqrstvwvyz")num = set("1234567890")count = 0Vcount = 0Ccount = 0Ncount = 0with open(ein) as ein_handle: for line in ein_handle: count += 1 for line in ein_handle: if line in vowels: Vcount += 1 elif line in cons: Ccount += 1 elif line in num: Ncount += 1print("the file has",count,"lines.")print("the file has",Vcount,"vowels.")print("the file has",Ccount,"consonants.")print("the file has",Ncount,"numerical characters.")

第二个循环应该针对给定行中的每个字符。
试试这个：
ein = input("Please enter file name: ")
vowels = set("AEIOUaeoiu")
cons = set("BCDFGHJKLMNPQRSTVWXYZbcdfghjklmnpqrstvwvyz")
num = set("1234567890")
count = 0
Vcount = 0
Ccount = 0
Ncount = 0
with open(ein) as ein_handle:
for line in ein_handle:
count += 1
for letter in line:
if letter in vowels:
Vcount += 1
elif letter in cons:
Ccount += 1
elif letter in num:
Ncount += 1
print("the file has", count, "lines.")
print("the file has", Vcount, "vowels.")
print("the file has", Ccount, "consonants.")
print("the file has", Ncount, "numerical characters.")
另外，在第二个循环内得到 0 （而不是行数）的主要原因是因为当第一个循环执行时，它会在每次迭代时更新读取偏移位置，直到它结束。因此，当第二个循环开始时，它从文件末尾开始，无法读取任何内容。

这是另一种方法：
import os
d,_ = os.path.split(__file__)
ein = input("Please enter file name: ")
vowels = "aeoiu"
cons = "bcdfghjklmnpqrstvwvyz"
num = "1234567890"
Vcount = 0
Ccount = 0
Ncount = 0
with open(d+"\\" + ein) as ein_handle:
lines = ein_handle.readlines()
for line in lines:
line = line.lower()
for v in vowels:
tmp = line
while v in tmp:
Vcount += 1
tmp = tmp[tmp.find(v)+1:]
for c in cons:
tmp = line
while c in tmp:
Ccount += 1
tmp = tmp[tmp.find(c)+1:]
for n in num:
tmp = line
while n in tmp:
Ncount += 1
tmp = tmp[tmp.find(n)+1:]
print("the file has",len(lines),"lines.")
print("the file has",Vcount,"vowels.")
print("the file has",Ccount,"consonants.")
print("the file has",Ncount,"numerical characters.")
