python print format函数的对齐与宽度设置技巧有哪些

左对齐：使用’<’

name = "John"age = 25print("{:<10} is {} years old".format(name, age))

右对齐：使用’>’

name = "John"age = 25print("{:>10} is {} years old".format(name, age))

居中对齐：使用’^’

name = "John"age = 25print("{:^10} is {} years old".format(name, age))

设置宽度：使用数字指定宽度

name = "John"age = 25print("{:20} is {} years old".format(name, age))

设置填充字符：使用指定填充字符

name = "John"age = 25print("{:_<10} is {} years old".format(name, age))

设置精度：使用’.’

pi = 3.14159print("{:.2f}".format(pi))
