【Python】字符串不足位數補零/補空格

一、補零

if __name__ == '__main__':
    str1 = '130000'
    for a in range(100):
        print(str1 + str(a).zfill(5)) 

 

二、補空格

2.1、rjust：右對齊

if __name__ == '__main__':
    str_1 = ['cscs', 'dad', 'a', 'adasdadadad', 'jdsad', 'aaaaaaaaaaaaaaaaaaaaaaaaaaaaaa']
    for s in str_1:
        print(s.rjust(30), ':', '11')

 

 

 2.2、ljust：左對齊

if __name__ == '__main__':
    str_1 = ['cscs', 'dad', 'a', 'adasdadadad', 'jdsad', 'aaaaaaaaaaaaaaaaaaaaaaaaaaaaaa']
    for s in str_1:
        print(s.ljust(30), ':', '11')

 

 2.3、center：居中對齊

if __name__ == '__main__':
    str_1 = ['cscs', 'dad', 'a', 'adasdadadad', 'jdsad', 'aaaaaaaaaaaaaaaaaaaaaaaaaaaaaa']
    for s in str_1:
        print(s.center(30), ':', '11')
