1、创建python代码，testread()file.py；
2、编写python代码，
import re
def getFileContent(str):
str_value = str
len_str_value = len(str_value)
print(str_value)
print(len_str_value)
len_capital = len(re.compile(r'[A-Z]').findall(str_value))
print(u'大写字母有%d个'%len_capital)
len_lowercase = len(re.compile(r'[a-z]').findall(str_value))
print(u'小写字母有%d个'%len_lowercase)
len_num = len(re.compile(r'\d').findall(str_value))
print(u'数字有%d个'%len_num)
len_others = len_str_value -len_capital-len_lowercase-len_num
print(u'其他的字符有%d个'%len_others)
dict1 = {'capital':len_capital,'lowercase':len_lowercase,'others':len_others,'num':len_num}
return dict1
if __name__ == '__main__':
str = open('D:\\test.txt','r',encoding='UTF-8').read().replace('\t','').replace('\n','').replace(' ','').replace('space','')
print(getFileContent(str))
3、右击‘在终端中运行Python文件’；
4、查看运行结果，满足需求；
#coding:utf-8
import re
def test(str_1):
str1 = str_1
len_str1 = len(str1)
print len_str1
len_capital = len(re.compile(r'[A-Z]').findall(str1))
print u'大写字母有%d个'%len_capital
len_lowercase = len(re.compile(r'[a-z]').findall(str1))
print u'小写字母有%d个'%len_lowercase
len_num = len(re.compile(r'\d').findall(str1))
print u'数字有%d个'%len_num
len_others = len_str1 -len_capital-len_lowercase-len_num
print u'其他的字符有%d个'%len_others
dict1 = {'capital':len_capital,'lowercase':len_lowercase,'others':len_others,'num':len_num}
return dict1
if __name__ == '__main__':
str_1 = open('c:\\test1.txt','r').read().replace('\t','').replace('\n','').replace(' ','').replace('space','')
print test(str_1)
>>> from collections import Counter
>>> c = Counter()
>>> for ch in 'programming':
... c[ch] = c[ch] + 1
...
>>> c
Counter({'g': 2, 'm': 2, 'r': 2, 'a': 1, 'i': 1, 'o': 1, 'n': 1, 'p': 1})
这是我用python3写的，字典老师还没讲……
a=input()
b="abcdefghigklmnopqrstuvwxyz"
m="0123456789"
c=str.upper(b)
d=0
e=0
n=0
q=0
h=0
z=len(a)
for i in range(z):
if a[i] in b:
d=d+1
elif a[i] in c:
e=e+1
elif a[i] in m:
n=n+1
elif a[i] in " ":
q=q+1
else:
h=h+1
print(d,e,n,q,h)
