替换敏感字符,统计,乘法表,函数

#!/usr/bin/env python
# -*- coding:utf-8 -*-

# 1.替换敏感字符
# keys = ['苍老师', '小泽老师', 'alex']
# with open('file.txt', mode='r', encoding='utf-8') as f1, open('2.txt', mode='w', encoding='utf-8') as f2:
#     for line in f1:
#         for a in keys:
#             if a in line:
#                 line = line.replace(a, '***')
#         f2.write(line)

# 2.统计各省车牌数
# cars = ['鲁A3244','鲁B12333','京B8989M','黑C49678','黑C46555','沪B25041','黑C34567']
# dic = {}
# for i in cars:
#     a = i[0]
#     if a in list(dic.keys()):
#         dic[a] += 1
#     else:
#         dic[a] = 1
# print(dic)

# 3.数据添加到字典.
# info = []
# with open('data.txt',mode='r',encoding='utf-8') as f1:
#     a = f1.readline()
#     for lines in f1:
#         dic = {}
#         i = lines.split(',')
#         count = 0
#         for k in a.split(','):
#             dic[k.strip()] = i[count].strip()
#             count += 1
#         info.append(dic)
# print(info)

# 4.小九九乘法表
# for a in range(1,10):
#     for b in range(1,a+1):
#         if a == b:
#             print(str(a) + '*' + str(b))
#         else:
#             print(str(a)+'*'+str(b),end=' ')

# 5.读取文件，将文件的内容构造成指定格式的数据，并返回。
# """
# a.log文件
#     alex|123|18
#     eric|uiuf|19
#     ...
# 目标结构：
# a.  ["alex|123|18","eric|uiuf|19"] 并返回。
# b. [['alex','123','18'],['eric','uiuf','19']]
# c. [
#  {'name':'alex','pwd':'123','age':'18'},
#  {'name':'eric','pwd':'uiuf','age':'19'},
# ]

print(func(1,6,8,7,1,2,4))
'''

# 传入n,返回n的阶乘.
'''
def func(n):
    res = 1
    for i in range(1, n+1):
        res *= i
    return res
