In addition,Python’s strings support the sequence type methods described in the Sequence Types — str, unicode, list, tuple, buffer, xrange section. To output formatted strings use template strings or the % operator described in the String Formatting Operations section. Also, see the re module...
>>> num = 4.123956>>> f"num rounded to 2 decimal places = {num:.2f}"'num rounded to 2 decimal places = 4.12'如果不做任何指定，那么浮点数用最大精度 >>> print(f'{num}')4.123956 格式化百分比数 >>> total = 87>>> true_pos = 34>>> perc = true_pos / total>>> perc0....
