统计下边这个长字符串中各个字符出现的次数

def search(*params):
    a = list(params)
    b = []
    for each in params:
        if each not in b:
            b.append(each)

    c = {}
    for each in b:
        c[each] = a.count(each)

    print(c)

search(' sdfdsf')

哪里不对呢...

*params就是考虑不定长参数，那就需要多一个循环
然后下面计数也要放进这个循环里

def search(*params):
    a = list(params)
    b = []
    c = {}
    for params_temp in a:
        for each in params_temp:
            if each not in b:
                b.append(each)
        for each in b:
            c[each] = params_temp.count(each)
    print(c)

search(' sdfdsf','sdaaa')

def search(params):

挥舞乾坤

def search(string):
    c = {}
    for e in string:
        c.setdefault(e,0)
        c[e] += 1
    return c

print(search(' sdfdsf'))

城中城

def search(*params):
    a = []
    for each in params[0]:
        a.append(each)
    b = []
    for each in params[0]:
        if each not in b:
            b.append(each)

    c = {}
    for each in b:
        c[each] = a.count(each)

    print(c)

search(' sdfdsf')

或者这样

def search(params):
    a = []
    for each in params:
        a.append(each)
    b = []
    for each in params:
        if each not in b:
            b.append(each)

    c = {}
    for each in b:
        c[each] = a.count(each)

    print(c)

search(' sdfdsf')

以修改 希望采纳

知我枯荣

f = open("string1.txt")
lines = f.read()
result = {x:lines.count(x) for x in lines}
print(result)
f.close()
