一、參考解法:
s =input('請輸入字符串:')
dic={'letter':0,'integer':0,'space':0,'other':0}
for i in s:
if i >'a' and i<'z' or i>'A' and i<'Z' :
dic['letter'] +=1
elif i in '0123456789':
dic['integer'] +=1
elif i ==' ':
dic['space'] +=1
else:
dic['other'] +=1
print('統計字符串:',s)
print(dic)
print('------------顯示結果2---------------')
for i in dic:
print('%s='%i,dic[i])
print('------------顯示結果3---------------')
for key,value in dic.items():
print('%s='%key,value)
二、參考解法:
tmpStr = input('請輸入字符串:')
alphaNum=0
numbers=0
spaceNum=0
otherNum=0
for i in tmpStr:
if i.isalpha():
alphaNum +=1
elif i.isnumeric():
numbers +=1
elif i.isspace():
spaceNum +=1
else:
otherNum +=1
print('字母=%d'%alphaNum)
print('數字=%d'%numbers)
print('空格=%d'%spaceNum)
print('其他=%d'%otherNum)
三、參考解法:
InPut = input('請輸入字符串:')
letters = [ ]
spaces = [ ]
digits = [ ]
others = [ ]
for i in iter(InPut):
if i.isalpha():
letters.append(i)
elif i.isspace():
spaces.append(i)
elif i.isdigit():
digits.append(i)
else:
others.append(i)
print('''
字母: {}, 個數: {}
空格: {}, 個數: {}
數字: {}, 個數: {}
其他: {}, 個數: {}'''\
.format(letters, len(letters), spaces, len(spaces), digits, len(digits),others, len(others)))
四、參考解法:
使用正則表達式 re.findall()
import re s = input('請輸入一串字符:') char=re.findall(r'[a-zA-Z]',s)#以列表類型返回全部能匹配的子串 num=re.findall(r'[0-9]',s) blank=re.findall(r' ',s) chi=re.findall(r'[\u4E00-\u9FFF]',s)#漢字的Unicode編碼范圍 other = len(s)-len(char)-len(num)-len(blank)-len(chi) print('字母',len(char),'\n數字',len(num),'\n空格',len(blank),'\n中文',len(chi),'\n其他',other)
五、參考解法:
使用正則表達式 re.match()
import re
def splitFunc( ):
tmpStr = input('請輸入字符串:')
charNum = 0
digNum = 0
spaceNum = 0
otherNum = 0
for i in range(len(tmpStr)):
if re.match('[a-zA-Z]',tmpStr[i]):
charNum +=1
elif re.match('\d',tmpStr[i]):
digNum +=1
elif re.match('\s',tmpStr[i]):
spaceNum +=1
else:
otherNum +=1
print('字符:',charNum)
print('數字:',digNum)
print('空格:',spaceNum)
print('其他:',otherNum)
splitFunc()
