python 使用 split()、strip()、replace() 等函数进行处理大小写

有以下字符串：

    strZen  = '''   siMPle iS bEtter thAn c0MplEx.
             eRr0rs Sh0uLd nEveR PasS sIlently.   
             n0w iS beTtER THan NeveR.  '''

    可以看出，字符串的内容并不工整，并且字母 'o'，被错误的写成了数字字符 '0'；

    使用 split()、strip()、replace() 等函数进行处理，并输出为如下格式：

    Simple is better than complex.
    Errors should never pass silently.
    Now is better than never.

strZen  = '''   siMPle iS bEtter thAn c0MplEx.
             eRr0rs Sh0uLd nEveR PasS sIlently.   
             n0w iS beTtER THan NeveR.  '''
strZen = strZen.strip().replace('0','o').split(".")
for i in strZen:
    print(i.title(),end='')

import re
strZen  = '''   siMPle iS bEtter thAn c0MplEx.
             eRr0rs Sh0uLd nEveR PasS sIlently.   
             n0w iS beTtER THan NeveR.  '''
strZen = strZen.replace("0","o")
a = re.findall(r"\S.*?\.",strZen,re.S)
a = [i.capitalize() for i in a]
print(*a)

strZen  = '''   siMPle iS bEtter thAn c0MplEx.
             eRr0rs Sh0uLd nEveR PasS sIlently.   
             n0w iS beTtER THan NeveR.  '''
strZen = strZen.replace("0","o").lower().strip()
a = strZen.split('.')
for s in a:
    if s:
        b=s.strip().split(' ')
        b[0]=b[0].title()
        c=' '.join(b)+‘.’
        print(c)
print(*a)
