Python 3.6+确实具有变量插值-
f在您的字符串前添加：
f"foo is {bar}"对于低于此版本的Python版本（Python 2-3.5），您可以
str.format用来传递变量：
# Rather than this:print("foo is #{bar}")# You would do this:print("foo is {}".format(bar))# Or this:print("foo is {bar}".format(bar=bar))# Or this:print("foo is %s" % (bar, ))# Or even this:print("foo is %(bar)s" % {"bar": bar})
