so we can use it with List. Also, the list should contain strings, if you will try to join a list ofintsthen you will get an error message asTypeError: sequence item 0: expected str instance, int found. Let’s look at a short example...

>>> sep.join(seq) # Joining a list of strings '1+2+3+4+5' >>> dirs = '', 'usr', 'bin', 'env' >>> '/'.join(dirs) '/usr/bin/env' >>> print('C:' + '\\'.join(dirs)) C:\usr\bin\env 可以看到,要连接的序列元素都必须是字符串。注意后面两个中的方法我使用一个目录列...
returnoutput_list 通过将列表长度计算移出for循环,加速1.6倍,这个方法可能很少有人知道吧。 # Summary Of Test Results Baseline: 112.135 ns per loop Improved: 68.304 ns per loop % Improvement: 39.1 % Speedup: 1.64x 3、使用Set 在使用for循环进行...

Another form of concatenation is with the application of thejoinmethod. To use the join method, we have to call it on the string that’ll be used for joining. In this case, we’re using a string with a space in it. The method receives a list of strings and returns one string with...
