[英]How do I fix “TypeError: can't multiply sequence by non-int of type 'float'” for my formulas?
[英]How do I fix this TypeError in Python concerning non-int and floats?
我正在Visual Studio Code上使用Python 3 ,我正在從事的項目是在接收到地球重量后計算用戶的月球重量,然后輸出他們的體重如何隨着時間的增加和一段時間的變化而變化。
這是我多次收到的錯誤消息,無論我重新編碼多少次:
TypeError: can't multiply sequence by non-int of type 'float'
每當我使用 input() 和/或 sys.stdin.readline() 函數時都會發生這種情況,但所有相關變量都是整數或浮點數,無論我是否嘗試使用 float() 函數將它們轉換為浮點數圍繞我的輸入。
這是我的代碼:
# this programs converts your terra weight to your lunar weight, then it takes increase over a period of time
# error whether I use float() or not
terraWeight = float(input("Terra Weight: "))
ask = input("Is this in LBS or KG? ")
# converts pounds to kilograms
# 2.204... is used to convert lbs to kgs
if ask == "lbs" or "LBS":
initial = terraWeight / 2.2046223302272
# didn't need this, but assignment error popped up
x = 0
# or replace input() with sys.stdin.readline()
increase = input("Increase: ")
period = input("Period: ")
# gets lunar weight over time
def lunarWeight():
global increase
global period
global x
global initial
print("Earth Weight = %s kgs." % terraWeight)
year = 0
lunarWeight = initial * 0.165
print("Moon Weight = %s kgs. \n" % lunarWeight)
postIncrease = lunarWeight * increase
for x in range(0, period):
year += 1
lunarWeight += postIncrease
print("Year %s = %s kgs." % (year, lunarWeight))
lunarWeight()
終端指向我代碼的這一部分:
postIncrease = lunarWeight * increase
第 28 行。我不確定問題是什么,我嘗試了調試,但仍然收到相同的錯誤消息。 我看到其他帖子有同樣的問題,但他們在使用列表時遇到了問題,我很確定我沒有使用。 請問有什么建議嗎?
我認為你應該把這行寫成:
increase = float(input("Increase: "))
period = int(input("Period: "))
期間在range()
使用,因此它應該是整數
