[英]If Statements and Setting Variables in Python
I'm trying to pass in df1
, df2
, df3
& df4
sequentially into the parseTwoPoleBreakers
function. 我正在尝试将
df1
, df2
, df3
和df4
依次传递到parseTwoPoleBreakers
函数中。 However, only df1
is being ran. 但是,仅
df1
正在运行。 Is there something wrong with my if
elif
statements that causing df2
, df3
& df4
to not be passed into the parseTwoPoleBreakers
function? 我的
if
elif
语句是否有问题,导致df2
, df3
和df4
无法传递到parseTwoPoleBreakers
函数中?
i=0
for j in range(0,4):
if j==0:
df=df1
elif j==1:
df=df2
elif j==2:
df=df3
else:
df=df4
#execute this for each dataframe
while (i<7):
parseTwoPoleBreakers(7,8,"ab",i,df)
breakerid+=1
parseTwoPoleBreakers(9,10,"bc",i,df)
breakerid+=1
parseTwoPoleBreakers(11,12,"ca",i,df)
breakerid+=1
i+=1
#j+=1
print j

Your problem is most likely related to variable scoping inside the if statements or the fact the while i < 7
isn't entered after df1
because i == 7
您的问题很可能与if语句中的变量作用域有关,或者在
df1
之后未输入while i < 7
的事实,因为i == 7
Use a list instead for the df
and did you mean to loop back over the 7 i
values? 使用列表代替
df
,是不是要循环返回7 i
值?
for df in [df1, df2, df3, df4]:
#execute this for each dataframe
for i in range(7):
parseTwoPoleBreakers(7,8,"ab",i,df)
breakerid+=1
parseTwoPoleBreakers(9,10,"bc",i,df)
breakerid+=1
parseTwoPoleBreakers(11,12,"ca",i,df)
breakerid+=1
